| Thehionn is the fourth planet from Kepler-540 and the second-smallest planet in its solar system.
The interior of Thehionn is mainly composed of ices and stone. This cold planet is named after the deity Thehionn, the spirit of the underworld.
Thehionn is gravitationally locked with Kepler-540 in a 2:1 spin-orbit resonance, and rotates in a way that is unique in its solar system.
The atmospheric pressure at the planet's surface is 0.06 bar, or roughly the pressure found 810 m under the oceans of Earth.
Surrounding Thehionn is a large planetary ring system and a powerful magnetosphere. |
