Fictional info (?)
Suggested nameParya-ji
Planet typeCold planet
It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.

This cold planet is named after the deity Parya-ji, the goddess of destruction.

Parya-ji is gravitationally locked with HD 10442 in a 5:4 spin-orbit resonance, and rotates in a way that is unique in its solar system.

Parya-ji's axis has the smallest tilt of any of its solar system's planets.

The smooth Borealis basin in the northern hemisphere covers 35 percent of the planet and may be a giant impact feature.

Observations from Earth have shown seasonal change and increased weather activity as Parya-ji approached its equinox 5 years ago.
