Suggested nameThedemi
Planet typePlanet
The planet is named after the deity Thedemi, the spirit of prosperity.

Thedemi's surface appears extremely cratered and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.

Thedemi is the site of Celestium Mons, the most active volcano and second-highest known mountain in its solar system, and of Valles Marineris, one of the largest canyons in its solar system.
