| Suggested name | Yuichu'sanyu |
| Planet type | Hot planet |
| Its orbital period around HD 213885 A of 4.8 earth days is the longest of all the planets in its solar system.
The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to HD 213885 A, which reoccurs over the so-called synodic period approximately every 58 days.
The polar regions are constantly below 207°K (-66°C).
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on. |
