| Suggested name | Unaf |
| Planet type | Cold planet |
| Unaf's atmosphere is similar to Nuramo's in its primary composition of xenon and nitrogen, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. This cold planet is named after the deity Unaf, the creator of the underworld.
Unaf was one of the first planets to have its motions plotted across the sky - as early as the second millennium BC. |
