| Suggested name | Weihyuan |
| Planet type | Huge cold gas giant |
| It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to @STARNAME, which reoccurs over the so-called synodic period approximately every 93 days.
It may have had ethane oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect. |
