| Suggested name | Mnepro Juldome |
| Planet type | Small cold gas planet |
| Orbiting within Tismas Sie's orbit, Mnepro Juldome is an inferior planet and never appears to venture far from GJ 273; its maximum angular distance from GJ 273 (elongation) is 84 degrees.
It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 43°K (-230°C), and has a complex, layered cloud structure with helium thought to make up the lowest clouds, and nitric oxide the uppermost layer of clouds. The planet is named after the deity Mnepro Juldome, the goddess of the sky.
Like Tismas Sie, Mnepro Juldome has been orbiting GJ 273 within Theus's orbit as an inferior planet, and never moves more than 15 degrees away from GJ 273.
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 160°K (-113°C) at night to 980°K (707°C) during the day across the equatorial regions. |
