| Suggested name | Togyachi |
| Planet type | Cold planet |
| It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 68°K (-205°C), and has a complex, layered cloud structure with oxygen thought to make up the lowest clouds, and sulfur dioxide the uppermost layer of clouds.
The polar regions are constantly below 234°K (-39°C).
Because of its fast rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). |
