| Suggested name | Ponyu-me |
| Planet type | Hot planet |
| It may have had helium oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
A prominent result is the "great black spot", a giant storm that is known to have existed for centuries since it was first seen by telescope. |
