| Suggested name | Chaupyu-so |
| Planet type | Cold planet |
| It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
The smooth Borealis basin in the northern hemisphere covers 25 percent of the planet and may be a giant impact feature.
Its north and south poles, therefore, lie where most other planets have their equators. |
