Gliese 422 b Gliese 422 b is an unconfirmed exoplanet orbiting the red dwarf Gliese 422 (Innes' star). Gliese 422 b was discovered in 2014. It has a mass of ten times that of Earth, and hence it may be a mega-Earth if solid or a mini-Neptune if gaseous. It is located within the circumstellar habitable zone (HZ) of Gliese 422, which extends from 0.11 to 0.21 astronomical units. Gliese 422 b's semi-major axis is astronomical units and its orbital period is Earth days. ==Habitability== Due to its high mass, Gliese 422 b is a poor candidate for life, because above 7 Earth masses, all liquid water would be compressed into a solid state.
