| Suggested name | Pubya |
| Planet type | Cold planet |
| It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 70°K (-203°C), and has a complex, layered cloud structure with hydrogen peroxide thought to make up the lowest clouds, and methane the uppermost layer of clouds. This planet is named after the deity Pubya, the spirit of destruction.
As seen from Kepler-1516, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
Pubya is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. It may have had carbon monoxide oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 8 meters. |
