| Suggested name | Byupya |
| Planet type | Hot planet |
| It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
Byupya and Gosonu Sakya are hot planets rich in rock. This hot planet is named after the deity Byupya, the bringer of the sky.
Like Gosonu Sakya, Byupya has been orbiting Kepler-280 for @STARAGE billion years, and never exceeds 11 degrees away from Kepler-280. The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to Kepler-280, which reoccurs over the so-called synodic period approximately every 133 days.
Byupya is by far the hottest planet in its solar system, with a mean surface temperature of 305°K (32°C). The nitric oxide has probably photodissociated, and the free ethane has been swept into interplanetary space by the solar wind because of the lack of a carbon dioxide layer.
Liquid water cannot exist on the surface of Byupya due to low atmospheric pressure, which is less than 8 percent of Gosonu Sakya's, except at the lowest elevations for limited periods.
Byupya has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Frontier flyby missions and later by the Galileo orbiter. |
