Suggested namePizenya
Planet typeCold planet
It is named after the deity Pizenya, the god of hate.

Pizenya is a cold planet and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to HD 29021, and bulk composition. Pizenya's surface is a dry desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.
