Suggested nameApugi'mua
Planet typeHot planet
Apugi'mua is the fourth planet from K2-229 and the second-smallest planet in its solar system.

This planet is named after the deity Apugi'mua, the creator of hate.

It is radically different from Wabyure'royu in other respects. It may have had 2H2O oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

Liquid water cannot exist on the surface of Apugi'mua due to low atmospheric pressure, which is less than 4 percent of Wabyure'royu's, except at the highest elevations for limited periods.
