| Suggested name | Rohakyo-sehi |
| Planet type | Cold planet |
| Rohakyo-sehi is similar in composition to Chon, and both have different bulk chemical composition from that of the larger cold planets. The planet is named after the deity Rohakyo-sehi, the god of nature.
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 50°K (-223°C) at night to 770°K (497°C) during the day across the equatorial regions.
As one of the most noticeable objects in the sky, Rohakyo-sehi has been a major inspiration in native culture for as long as records have existed.
Future astrobiology missions are planned, including the Rohakyo-sehi 1100 and ExoRohakyo-sehi rovers.
Its apparent magnitude reaches -3, which is surpassed only by Chon, Bakabe-ko, and Kepler-488. |
