| Suggested name | Chikomyo |
| Planet type | Small hot gas planet |
| Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 135°K (-138°C) at night to 735°K (462°C) during the day across the equatorial regions.
It has the densest atmosphere of the known small hot gas planets, consisting of huge amounts of krypton.
The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. |
| Atmosphere | Krypton | 85% |
| Molecular hydrogen | 7.9% |
| Hydrogen peroxide | 4.7% |
| Helium | 2.2% |
| Oxygen | 0.039% |
| Nitrogen | 0.0047% |
| Atmospheric pressure | 0.001 bar |
