| Suggested name | Chuku |
| Planet type | Cold planet |
| Its orbital period around RR Cae (AB) of 5500 earth days is the shortest 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 RR Cae (AB), which reoccurs over the so-called synodic period approximately every 133 days.
It has the densest atmosphere of all the cold planets, consisting of huge amounts of krypton. It may have had hydrogen chloride oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. |
