Also contains oxygen. Billions of years ago was cooler and likely had liquid water Evidence of Previous water. Possibly frozen water. Surface entirely frozen, but most likely liquid water underneath Some evidence for small amounts of frozen water. Very thick, mostly Massive greenhouse CO2. Contains effect could have Sulfuric Acid. dried up the planet. Frozen water present, likely liquid water underneath Numerous planets possible, perhaps with oceans just like that of the Earth Thick, rich in Nitrogen Thin, mostly CO2. Evidence of past Contains traces of tectonic activity. methane. Already landed robotic rover. Very thin, Hydrothermal vents composed mostly under frozen surface of oxygen are likely to exist Very Thin, composed of mostly Sulfur Dioxide Numerous planets possible, perhaps with atmospheres just like that of the Earth Only other body in solar system with known active volcanism. Composition similar to terrestrial planets. Produces products like ethane and other fuels as precipitation. Entire star system, consisting of numerous stars possibly an entirely new solar system. Anything discovered here would be a historical first. *Earth has been added only for ease of comparison. Data has been acquired from the following sources: http://theanswermachine.tripod.com/id2.html http://nssdc.gsfc.nasa.gov/planetary/factsheet/ Other Info: Water Freezes at 273 K, Boils at 373 K Kelvin + 273 = Degrees Celsius Temperature listed is only the surface temperature. Temperature will increase as you move below the surface. This increases possibilities for liquid water under the surface, especially on locations with thermal vents or tectonic activity.
