| Suggested name | Vosnome |
| Planet type | Cold planet |
| It is the second-brightest natural object in the night sky after Fenliaq Pho, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, sometimes, visible to the naked eye in broad daylight.
The planet is named after the deity Vosnome, the creator of fear.
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 175°K (-98°C) at night to 735°K (462°C) during the day across the equatorial regions.
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
The rotational period and seasonal cycles of Vosnome are likewise similar to those of Fenliaq Pho, as is the tilt that produces the seasons.
The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. |
