Innes' star /ˈɪnɪs/ (Gliese 422) is an M3.5-type red dwarf,[1][5] located in constellation Carina.

[6] It has around 35% of the mass of the Sun, yet only 1.1% of its luminosity, and an estimated surface temperature of 3,323 K.[5] Innes' star was discovered in 1920 by Robert T. A. Innes in Union Observatory, Union of South Africa, who had discerned its large proper motion and a parallax of 0.337 arcsec.

[9] However, UO designations should be used with caution since they are often not unique for each star: the number in the name is the number of Circular, so all stars published in one Circular have identical names.

It is known for the fact that it had once been considered one of the nearest stars to Earth, due to erroneously measured parallax.

[1] In 2014, a Mega-Earth or a mini-Neptune, GJ 422 b, of approximately ten Earth-masses, was discovered in the system of this star, orbiting the star every 20 days and lying at a distance of around 0.11 astronomical units (AU)—11% of the distance between the Earth and Sun—on the inner edge of the stellar system's habitable zone, which for this star has been calculated to lie between 0.11 and 0.21 AU.
