| Planet type | Cold planet |
| It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 33°K (-240°C), and has a complex, layered cloud structure with 2H2O thought to make up the lowest clouds, and carbonyl sulfide the uppermost layer of clouds.
The smooth Borealis basin in the northern hemisphere covers 20 percent of the planet and may be a giant impact feature. |
