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 6999119000000000000♠0.119+0.014
−0.011 astronomical units and its orbital period is 7001261610000000000♠26.161+0.082
−0.098 Earth days.
