Well that the data I have. what can we say, well extreme temperature fluctuations for one, these would I suspect be the reason for the atmosphere being the way it is, its normal between -25 and 50 degrees C, i'm taking that to mean that at those temperatures its breathable, but at hight or lower than that it becomes toxic or corrosive.
This might explain why there is actually native life on this world.
Gravity is only marginally higher than earth standard.
It has chemical oceans, 90% of its surface is covered, that has interesting visual conotations.
It has a large sister world or moon if you like, equally if not more nasty than itself.
I'm leaning towards mining as the main idea, there might be exotic chemical compounds in the atmospheres of the world and its moon, I don't know.
What do you think CELS, is it beyond redeption.
Oh and this is the Moon

Well... it would be nice to know more about the atmosphere and the hydrosphere. Did the program write 'Normal, 25-50 C'? The extreme changes in temperature are very, very interesting. It's also interesting to see that the surface is 90% water, despite the extreme summer temperatures. The equator goes from -19 to 125 degrees celsius in 45 standard days. This should have an interesting effect on the oceans, which would boil unless there's a high percentage of some other chemical in the water which prevents it from boiling.
Very interesting, Dazo, but we need more information to know whether or not this could be an Imperial world. Maybe get Destecado or someone else with some insight in science to help out.
At any rate, it doesn't seem as if this world will be anything more than a mining world... Or could we increase the population enough to make it a civilised world or even a hiveworld?

Thats exactly what it wrote, and thats -25 to 50 degrees C, which on this world seems to be not as easy as it might appear, its only got a yeah thats 43 days long, so summer and winter must meet each other coming the other way, the planet probably changes colour as the temperature cause the different gases to become active. What those gases would be is a mystery.
Yep I would imagine they do, this is probably when the atmosphere becomes corrosive, as the oceans are 90% not water but probably bleach or acid. So summer would bring thinck corrosive fog and turn the planet white. whereas in winter something else would happen, though winter does appear to be the more hospitable time as far as the atmosphere's concerned
It also has an axial tilt of 90 degrees, does that mean its actually orbiting on its side.
I agree, though I have some vague ideas of my own it would be helpful to have an expert opinion.
Glass, glass resists acid, so maybe all the buildings are made of glass, or some other silicon based product. With large glass light traps which rise above the fog to trap sun light and redirect it to the surface, perhaps for hydroponic purposes.

What those gases would be is a mystery. Of course, it can't really remain a mystery. But you know that  Let's discuss the colours after we know a bit more about the chemicals  Well, let's hear them! What's in the atmosphere, and what effects would the atmosphere and hydrosphere have on the world and the life on it? Well, at least they could be covered with glass Let's not get too fantasy |

I know that, what I meant was at the moment its a mystery Now the gases that spring to my mind are Ammonia Methane Halides(chlorine/flourine/bromine) benzine(the one destecado suggested for your world) sulphur dioxide(forms acid rain) Now the temperature swing might allow for several different atmospheres at different times of the year. Colour is highly indicitive of the chemical, lets say I fancy an orange world, that would indicate possible similarities with the atmosphere of titan, so that would be a nitrogen/methane mix, or perhaps I fancied a lime world, that might mean an atmosphere of chlorine or flourine. Thats how I figure things out, its not that i'm trying to be poetic or anything. Well in the corrosive atmosphere that might exist during the summer(I would say months but the year is only 46 days long) days, you might not be able to go out onto the surface at all, so subterranian mining would be a god bet. But during the "winter" the atmosphere would only be an irritant, so you could move about on the surface, and possibly mine/quarry/extract stuff that otherwise would be inaccesable in summer. And I don't see this a gentle transition, but a sudden violent change with great walls of acid fog roaring out from the equatorial regions, if there are any...what with the 90 degree tilt and all. yep, plasteel sheathed in glass sort of thing, I want the towers though, they would be more like needles really, as I think they would be cool. Is it to much to hope that this world would be under the wing of the Adeptus Mechanicus, all mod cons and all that. I'm pretty sure they would want direct acess to the vast wealth of the planet if they possibly could. |

Rapid increase in temperature you say.....Of the top of my head, this could perhaps be explained by one of two things. If you have the planet as a moon of a larger body, it may be that there is another moon that passes close to it.
It could be that this moon orbits faster than the planet were are discussing or maybe it is in a retrograde orbit (orbits backwards). Usually in the case of a retrograde orbit it could be a captured stellar body. the increae in temperature may occure as the moons pass each other.
The increased tidal stress would raise the temperature...although I'm not to sure about the drastic increase we are seeing (I'll have to look into it a little more). It may cause an increase in vulcanic activity as well and since most of the planet is covered in water, this would heat up the oceans. As they move further apart, the temperatures return to normal.
The other case would be a binary system. The planet orbits one of the stars in the binary system, but during part of its orbit, it may move closer to the other star, which would have drastic changes on its temperature.
Both cases will cause a heating of the oceans, which is where I think we can get our hazordous atmosphere from. The oceans of earth contain vast quantites of disolved carbon dioxide. Part of the worry of global warming is that as the temperatures of the oceans increase, this disolved CO2 will be released into the atmosphere.
CO2 is a green house gas. It is feared that if too much is released, we will soon have a runaway greenhouse effect, that could make earth's atmosphere more like the one found on Venus. Of course this is but one theorized outcome of global warming (others think that global warming may lead to a new ice age), but a rise in the temperature of the oceans causing an outgas of disolved CO2 (and other gasses) is quite valid.
If enough CO2 is released into an atmosphere, it will eventually reach toxic levels. An individuals ability to draw in enough oxygen will be diminished. The change occurs too rapidly for organisms to adapt. Unable to draw enough oxygen from the air, organisms will begin to suffocate.
The now abundant CO2 in the atmosphere could combine with other chemicals such as sulfur to make acids, leading to acid rain. So not only would your inhabitants have difficulty breathing, they may also have to deal with rain that irritaes or even burns their skin.

Or its because its orbiting the star on its side, would that not make it sort of tidally locked.
If it was CO2 like the atmosphere of venus it wouldn't have rapid temperature swings as the greenhouse effect(and for Co2 to be toxic there would have to be alot of it) would actually stabalise surface temperature would it not. Yes the temperature might be made to rise by its massive moon, but it wouldnt lose heat fast enough for the drop we see in the temperature. Or am I wrong, would the size of the planet negate the effects of the Co2.
We would need a gas that didn't hinder the transmission of heat.

Or its because its orbiting the star on its side, would that not make it sort of tidally locked. It doesn't really matter if the planet is orbiting on its side or not. Tidally locked refers to a condition which occurs in astronomical bodies such as planets and moons that orbit each other closely. It results in the orbiting bodies synchronizing their rotation so that one side always faces its partner (or places them in orbital resonance). Since the star being orbited is a red dwarf, it is more than likely that a habitable planet will be tidally locked with it (the habitable zone for red dwarf stars is the 0 orbit). If it was CO2 like the atmosphere of venus it wouldn't have rapid temperature swings as the greenhouse effect(and for Co2 to be toxic there would have to be alot of it) would actually stabalise surface temperature would it not. I was trying to say that the outgassing of dissolved CO2 from the oceans might account for the rapid rise in temperature, that would make the world more like Venus. I was not trying to say that it was like Venus. The large oceans present on the planet would eventually reabsorb the CO2 bringing the temperature down. As to toxic levels of CO2, Carbon Dioxide normally makes up .03% of the air. If the CO2 content rises to as little as 10% it can be fatal. Still At the time i came up with this as an explanation, I had not taken a look at the fact that the Atmosphere of the planet is suppose to be corrosive. CO2 alone would not account for the corrosiveness of the atmosphere. Still there are other volcanic gasses that may increase the corrosivness of the atomosphere. What is the volcanic activity on the planet like? Yes the temperature might be made to rise by its massive moon, but it wouldnt lose heat fast enough for the drop we see in the temperature. Or am I wrong, would the size of the planet negate the effects of the Co2. Well if the planet is tidally locked, the "dark side" would be cool, the rise of greenhouse gasses and increase in tempreature could generate strong winds and currents that might draw the warm (CO2) ladened air and warm water to the dark side of the planet. The dark side of the planet in effect acts as a large heat sink for the light side...this would allow the oceans of the dark side to remain liquid. it may be that the mixture of cold air and warm air around the planet causes storms. If there is subsequent volcanic activity, maybe the sulfur or other chemicals given off in the outgassing fall back to the planet as rain...It may rain sulfuric acid on the dark side. Is that corrosive enough? I still at a loss to explain the rapid shifts in temperature unless there is some other outside source that perhaps heats the dark side increase the temperature on the light side beyond the capacity of the dark side to compensate. What about having a gas giant as a close companion to the red dwarf star. It could be that the planet orbits the gas giant, which in turn orbits the star. The rapid increase in temperature might occur when the planet swings around the gas giant and is directly exposed to the sun. As its orbit carries it around the back of the gas giant, it has a chance to return to normal. It may be that the gas giant was a failed binary companion of the red dwarf or during the formation of the solar system, two seperate bodies (the red dwarf and the gas giant) formed. If they had been one stellar body, the star would have been much larger and may have even been of a different class, but it instead split (or never came together) during its formation. We would need a gas that didn't hinder the transmission of heat. Not necessarily. Again, it all comes down to how the planet and system interact (see above). Being a satelite of a gas giant, may allow us to place the planet slightly outside of the normal habitable range of a red dwarf star. The planet would receive some warming from the Gas Giant in the form of radiation as well as from the volcanic activity caused by tidal stresses. As it swings in close to the sun, it would gain additional warming and illumination. It would still need to have a way to retain the heat so that as it swung away frm the sun it did not cool too quickly. The oceans may absorb alot of this heat (from solar radiation as well as from undersea volcanos, so that they act as a thermal pump to keep the planet warm. |

I meant that the effect would be the same, the planet is rotating, but on its side, meaning one of its poles would be constantly facing the star.
We are looking at a turn around of 23 days tops, can that much gas on a planet this big be absorbed sufficiently back into the oceans within 23 days.
This liquid, would it be carbonic acid, what with all the Co2 in the atmosphere, and can carbon monoxide be present in an atmosphere that has such large concentrations of Co2.
Is it cold enough on the dark side for Ice to form, would it be frozen acid, or would it be dry ice
Yes storms would be good, but how powerful would they be, I don't want them so powerful that all that stands before them falls. Am I right in assuming this world would be quite cloudy with low visability, or would it appear not to dissimilar to earth, ie you would be able to see the ground from space.
What if we included flourocarbons, err I think they use them in fridges...to err lower...the...err temperature...maybe. Is that bad science or what
The planets moon is only 1000 miles smaller than itself, an eclipse would be pretty much total every time, and if the moon has a slow orbit then the temperature drop could be caused by the moon blotting out the sun.
We seem to be coming up with lots of reasons, all of which could actually be responsible, might we not simply say the fluctuations are the result of the culminative effects of all these different scenarios

We are looking at a turn around of 23 days tops, can that much gas on a planet this big be absorbed sufficiently back into the oceans within 23 days. Even rotating on its side with one pole facing the sun would not account for such a radical change in temperatures. As to a 23 day window, why such a sort time for such large changes in temperature? I doubt that the gas would be able to be reabsorbed by the planets oceans in that short a time frame... This liquid, would it be carbonic acid, what with all the Co2 in the atmosphere, and can carbon monoxide be present in an atmosphere that has such large concentrations of Co2. It is possible, but rarely naturally occuring except in say a forest fire. It mostly occurs from the incomplete combustion of carbon and carbon containing compounds. Cyanide may be an alternative. Cyanide can be inorganic or it can be produced from organic sources. Inorganic cyanides contain a carbon atom triple bonded to a nitrogen atom. They can mix with Hydrogen to form Hydrogen Cyanide (HCN). Hydrogen cyanide is highly poisonous. It is colorless and has a faint, bitter, almond-like odor. Hydrogen cyanide is weakly acidic. Hydrogen cyanide is produced in large quantities all over the world by the chemical industry where it is used in tempering steel, dyeing, explosives, engraving, the production of acrylic resin plastic, and other organic chemical products. It can be produced by reacting a cyanide salt with a strong acid, or directly from ammonia and carbon monoxide.... Actually I was thinking that we could include ammonia in the atmosphere and have naturally occuring cyanide, but it is too much of a base. Since the atmosphere is corrosive, this would not really fit. Organic cyanides contain the CN group single-bonded to another carbon atom and are also known as nitriles. Two cyanide ions can bond to each other via their carbon atoms, forming the gas cyanogen. Cyanides can be produced by certain bacteria, fungi, and algae, and are found in a number of foods and plants. Cyanide occurs naturally in cassava roots, which are potato-like tubers of cassava plants grown in tropical countries; these must be processed prior to consumption. Fruits which have a pit, such as cherries or apricots, often contain either cyanides or cyanogenic glycosides in the pit. Bitter almonds, from which almond oil and flavoring is made, also contain cyanide. It could be that the hot warm enviroment and rapidly increasing temperatures promote an increase in the growth of these bacteria, algae and funguses. This in turn increases the amount of cyanide given off. A Hydrogen Cyanide concentration of 300 parts per million of air will kill a human within a few minutes. The lethal dose for adults is 50 mg of hydrogen cyanide compared with 200–300mg of potassium or sodium cyanide. Symptoms of moderate poisoning include vomiting, convulsions, deep breathing, shortness of breath and anxiety; more serious cases result in convulsions, loss of consciousness, and death after apnea and heart arrest. Is it cold enough on the dark side for Ice to form, would it be frozen acid, or would it be dry ice The surface temperature of a block of dry ice is about -109.3 degrees F (-78.5 degrees C). I don't think it gets that cold on the dark side. I also have some reservation as to how the system is set up currently, I think we need to still consider having the system be a binary. If the planet is orbiting the red dwarf in its habitable zone, then it is probably within its first orbit. It will therefore orbit the star fairly quickly (although it may still be longer than 23 days). It could be that the red dwarf blocks the planet from a brighter companion when it is behind it. As it orbits around the red dwarf, it comes into the light of this brighter star, which increase the amount of solar radiation the planet absorbs. This additional light would increase the temperature steadily as the planet moved in front of the red dwarf. The temperature would begin to fall of again as it moved back behind the red dwarf (which would eclipse the other star). Actually this may allow the planet to be out of what would normally be considered the habitable range for a red dwarf star, perhaps putting it into the first orbit rather than the zero orbit. Scientists have found some astronomical objects that were previously catagorized as pulsars may actually be binary star systems. In a binary system, apair of stars are held together by their mutual gravitational attraction and revolve about their common center of mass. An eclipsing binary has the plane of its orbit lying near the line of sight, and shows a periodic fluctuation in brightness as one star passes in front of the other. The more massive star (A) of a binary is called the primary, and the less massive (B) is called the secondary (this would be the red dwarf star). It seems likely that more than two-thirds of the stars in our galaxy are part of a binary or multiple (a system of more than two stars moving around their mutual center of mass) pairing, since many stars within 30 light-years of the sun are binary or multiple. What if we included flourocarbons, err I think they use them in fridges...to err lower...the...err temperature...maybe. Is that bad science or what. Good thought, but Fluorocarbons rarely occur naturally. Of course this is terrestrially speaking, but I don't think an enviroment where they could occur naturally would be conducive to life. As far as I can tell based on earlier osts, the concept is to have a breathable atmosphere...at least part of the time. The planets moon is only 1000 miles smaller than itself, an eclipse would be pretty much total every time, and if the moon has a slow orbit then the temperature drop could be caused by the moon blotting out the sun. The time frame would not be long enough for radiant cooling to remove all of that heat. Your also talking about plunging the planet into almost total darkness. I would need to do more calculations in order to see if the is feasable, but I still think we should go with the binary star system concept. |

Hmmmm Des you know a lot of things that taste like almonds?
Arsenic tastes like almonds too and is also poisonous!
With a thin atmosphere like this planet hs the winds are going to be very fierce...with the light/dark sides to the planet the change in temp will have hurricane winds blowing almost continously! Maybe faster!
The thing is having one pole pointing at the star at all times it will become VERY Hot here, boiling most chemicals into the atmosphere.
CO2 diffuses naturally into water, more so at higher temps, but not that quickly.
I am starting to wonder how pleasant this world would actually be, and if I should invest in times shares?

Hmmmm Des you know a lot of things that taste like almonds? Arsenic tastes like almonds too and is also poisonous! Actually Arsenic by itself has no taste or odor, that is why in centuries past, it was the poison of choice. If you burn arsenic, it does give off a garlicy odor...along with white smoke. Arsenic is a mineral rather than an organic compound like salt and other minerals, it readily disolves in water. Arsenic contamination of ground water is a serious problem in many place of the world. With a thin atmosphere like this planet hs the winds are going to be very fierce...with the light/dark sides to the planet the change in temp will have hurricane winds blowing almost continously! Maybe faster! Thin Atmosphere? True it is a little below earth standard, but falls well within the standard atmospheric range of .71 - 1.49. The only reason that the planet has any breathable atmosphere at all is due to the large amount of water, which it is slowly losing over time. As the atmosphere heats, more water vapor would be releleased into ther air. This could recombine into other compounds allowing the lighter weight molecules to escape out of the atmosphere. Maybe this world is on its way to becoming like venus...its just that enough time hasn't passed. CO2 diffuses naturally into water, more so at higher temps, but not that quickly. Actually its the other way around. Cold water can hold more disolved CO2 than warm water. |

Thats how long winter lasts, as does summer, the year is only 46 days long
Quite right, so no ice at all then, unless acid freezes, or would the water just freeze out, in effect purifying it.
Would conditions on this world actually be able to support enough life natural cyanide to occur that way, or in such large quantities.
The same applies to industrial versions of cyanide, is there actually enough industrial activity taking place to warrent such high levels of the poison.
I must say I did think about cyanogen, but i'm using it on another world so I wanted to make this world different. But if you think conditions could be right for this gas to form then we'll use it and i'll change the other world.
While I like the idea of binary systems the problem is the temperature rise would be even greater, possible so high the oceans wouldn't boil they would explosivly sublimate. and I don't know how to work out temperature, and what effcts would this have on the other worlds in the system. So if you know how to work it all out then we'll give it ago and see what happens
Would it not be simpler to have the planet in a more eliptical orbit with it approaching cloesr to the star in summer and moving further away in winter
Yep that was my thoughts on it aswell, with the cold pole on the other side and somewhere in between you would have your magic spot where the atmosphere was just right for life. But the weather wouldn't really allow this as it would be moving the deadly parts of the atmosphere into the good parts.

Base on the short time it takes the planet to orbit the sun, your idea of an eliptical orbit might work best for this world. It is simple and elegant and may give us the conditions we need without a lot of heavy mathmatical computations...<shudders>  We can save the binary star system concept for another world. Any thoughts on whether or not the eliptical orbit will cause the year to lengthen slightly? we'll probably want an eliptical orbit that is pretty extreme. It may be that at its furthest distance from the star, the planet is at the very edge of the habitable zone...or maybe even a little beyond it. Can such an extreme eliptical orbit occur normally or are outside factors required to causit? Maybe it was a captured planet or maybe its satellite, which is almost the same size was a rogue planet that do to a collision lost enough velocity to be captured by the gravitational field of the planet. As to the cyanide, go ahead and use it on the other world. After further consideration it really doesn't apply hear. We are looking for a corrosive atmosphere rather than a toxic one. I have a couple of other ideas that I will explore to explain the atmosphere... |

Earths orbit is slightly eliptical, not extremely so, but it shows that such orbits are possible, not only that but as I understand it they are the norm. A perfectly circular orbit would actually be highly bizarre.
The eliptical orbit of pluto actually brings it inside the orbit of neptune, so again yes I would say it was highly probable.
I would assume so, I have no problem altering the numbers for that, 46 day years are just not right, so if this gives me a reason to increase the lenth of the year then great. But not to the extreme maybe increase it to 148 days (4 times the origional lenth and so maybe giving us four seasons)
The world is not volcanically active to any great extent nor is there much in the way of heavy industry(at least not yet there isn't as I still havn't decided on a concept as such) so if theres some other naturally occuring corrosive gas or compound then that should do. Incedentally what would you need for nitric acid to form, or hydroflouric acid(which is used for etching glass I think).
