| Suggested name | Isohi |
| Planet type | Cold planet |
| In English, Isohi is often referred to as the "gray planet" because the nitrogen prevalent on its surface gives it a pale gray appearance that is distinctive among the astronomical bodies visible to the naked eye.
It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 50°K (-223°C), and has a complex, layered cloud structure with nitrogen thought to make up the lowest clouds, and carbonyl sulfide the uppermost layer of clouds. It is named after the deity Isohi, the bringer of nature.
Isohi is primarily composed of carbonyl sulfide with a significant part of its mass being nitrogen, though nitrogen comprises only about a limited fraction of the number of molecules.
In late February 2700, Isohi was visited by the New Horizons probe, which used Isohi's gravity to increase its speed and bend its trajectory en route to Elthys Fariara. |
