actually only mars and Titan (moon of saturn) seems to have a atmosphere with slight similarity to the earth but none of them have water in them
Many people think mars can be made earth in the future because it has ice in its poles but I say it is wrong because the ice in the poles may be dry ice ( solid state of carbon dioxide) as carbon dioxide forms most of its atmosphere

No known planet in our solar system or outside it has the same atmosphere as Earth. Mars certainly does not. But Mars does have water. It is all frozen, at he poles or under ground though. There is a planet in another solar system where water has been detected in its spectrum, but that planet is closer to its star than Mercury is to our sun and any water there would be in the form of thousand degree steam.

There are no planets in our solar system that we know off that have an atmosphere like earth. However just recently a planet by the name of HD 209458b which is a planet similar in size to that of Jupiter and located around 150 light years away in the constellation Pegasus that has been found to contain large amount of water in its atmosphere. This water is thought to have come from the impacts of comets on its surface. If the planet is similar in size to that of Jupiter then its gravitational pull would be enormous and would suck in a lot of material if that material would to stray to close.
Earth has water in the form of water vapour which helps trap heat and keeps our planet habitable in its atmosphere (3%) So at present this new planet is the only planet that comes close in terms of an atmosphere like ours. Other planets like Venus and Mars gave atmospheres rich in carbon dioxide, but make up over 96% of their atmosphere whereas with Earth it makes up about 0.04%
The atmosphere of Titan (Saturns largest moon) is made up of mostly Nitrogen (80-90%), which is very similar to Earth's atmosphere which is 78% nitrogen. Titan's atmosphere is very dense, and the air pressure at the surface is even higher than Earth's atmospheric pressure, but it is not a planet just a humble moon.

If I remember correctly we have found huge numbers of planets out there in other systems. Thousands? There was a report on the internet news of a planet with similar kind of atmosphere, water vapor, but it was huge and close to it's star.

Jupiters moon Europa has an ice surface with water under.
The athmosphere is 100% oxygen.
It has been suggested there is life on Europa in the water.
Check out the wikipedia.

No planet in our solar system has the same atmosphere as Earth. As for extra-solar planets, they have just found one where water is present in its atmosphere, called HD209458b.

There might be millions in our universe , but none in our solar system which has same atmosphere. As far as water is concerned, the Europa ( satellite of Jupiter ) has large water bed but the temperature is very low max. -173 min -194... But there is no air ;-)

No planets in our solar system have the atmosphere of Earth. They are still trying to determine which planets have water...all of which will be in the form of ice, no liquid.

No known planets anywhere have the same atmosphere as Earth. We know little about the more distant planets, so one somewhere might have the same air.

This argument has been presented up in diverse incarnations. the base line question? the position did the SCIENTIST come from. no longer some thing technological understanding has arise with has ever been waiting to describe the starting up of the starting up. This hypothetical problem is not any diverse. ============== pricey Uncle (LOL): yet why do you've self assurance that THEY believed the earth replaced into flat? because of use of a time period like "the 4 corners of the earth" as i have considered used the following? can we no longer use that similar time period on the instantaneous. Does someone who makes use of it on the instantaneous trust in a flat earth? have you ever examine activity 26:7 the position he refers back to the guy who's "putting the earth upon no longer some thing", this at a time at the same time as truly the option replaced into the classic medical concept? do not get me incorrect, stretching our understanding is an truly sturdy project. yet outlandish theories used to describe some thing extremely straightforward makes no experience IMVHO.
