Teegarden's Star has 2 possibly terrestrial planets orbiting it, Teegarden's C and Teegarden's B. B has an Earth Similarity Rating (ESI) of 0.95, compared to Earth's 1.00. This makes B one of the most likely candidates for interstellar colonization as it is only 12 light-years away. C has an ESI of only 0.68, but that is still pretty good. This means that by going to Teegarden's Star, there are 2 possible places to make a colony.
