Fictional info (?)
Suggested nameThel Pa
Planet typeCold planet
When viewed from Pros One, Thel Pa can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. The interior of Thel Pa is mainly composed of ices and rock. This cold planet is named after the deity Thel Pa, the spirit of good fortune.

An observer on Thel Pa would therefore see only one day every two years.

Thel Pa is by far the hottest planet in its solar system, with a mean surface temperature of 239°K (-34°C). Thel Pa's surface is a barren desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.

It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
