Teegarden c

Teegarden c is an exoplanet orbiting Teegarden's Star, a red dwarf located approximately 12 light-years from Earth. Discovered in 2019 alongside Teegarden b, it is slightly larger than Earth and orbits the star every 11.4 days. Teegarden c lies just outside the inner edge of the habitable zone, making it less likely to support liquid water on its surface compared to Teegarden b. However, its relatively close proximity to our solar system makes it a valuable candidate for further astronomical study.
