| Inum is the fourth planet from @STARNAME and the second-smallest planet in its solar system.
Inum's atmosphere is similar to Ered Ehuq On's in its primary composition of xenon and hydrogen chloride, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. The planet is named after the deity Inum, the creator of nature.
Inum is gravitationally locked with @STARNAME in a 4:3 spin-orbit resonance, and rotates in a way that is unique in its solar system.
Two spacecraft have visited Inum: Daedalus 3 flew by 32 years ago; and Messenger, launched 19 years ago, orbited Inum over 125 times in four years before exhausting its fuel and crashing into the planet's atmosphere 6 years later.
Inum's surface is a arid desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism. |
