| Suggested name | Toymir |
| Planet type | Cold planet |
| 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 ammonia thought to make up the lowest clouds, and ethane the uppermost layer of clouds.
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. |
| Atmosphere | Ethane | 55% |
| Ammonia | 13% |
| Carbon monoxide | 13% |
| Nitric oxide | 8.3% |
| Hydrogen peroxide | 4.9% |
| Water vapor | 4.4% |
| Methane | 0.78% |
| Sulfur dioxide | 0.00011% |
| Atmospheric pressure | 0.8 bar |
