| Cold planet |
| Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 115°K (-158°C) at night to 455°K (182°C) during the day across the equatorial regions.
It may have had water vapor oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
The smooth Borealis basin in the northern hemisphere covers 17 percent of the planet and may be a giant impact feature. |
