Dazhbog

Dazhbog (GJ 876 d) is the innermost planet in the Buyan system. Dazhbog is a large terrestrial planet, almost seven times the mass of Earth. Due to its close orbit around its host star, Dazhbog is incredibly geologically active, with an atmosphere filled with clouds of sulphur and other noxious chemicals. Because of this, many rare minerals are brought to the planet's surface for mining.
