Teegarden's Star c (also known as Teegarden c) is an exoplanet found orbiting in the habitable zone of Teegarden's Star, an M-type red dwarf star 12.5 light years away from the Solar System. It orbits in the conservative habitable zone around its star. Along with Teegarden's Star b, it is among the closest known potentially habitable exoplanets.^[2]^[3] It was discovered in June 2019.^[4]
