According to the Hertzsprung-Russell diagram, a red dwarf star is a small and relatively cool star, of the main sequence, either late K or M spectral type. They... red dwarf, a class of low temperature and low luminosity stars. This would explain why it was not discovered earlier, since it has an The apparent magnitude (m) of a star, planet or other heavenly body is a measure of its apparent brightness; that is, the amount of light received from the object. Hundred times less bright (e.g. the same object ten times as far) corresponds to an apparent magnitude that is five... apparent magnitude of only 15.4 (and an In astronomy, absolute magnitude is the apparent magnitude, m, an object would have if it were at a standardized distance away.

However, even at that time the anomalously low luminosity (the absolute magnitude would have been 18.5) and high uncertainty in the parallax suggested that it was in fact somewhat farther away, still one of the Sun's nearest neighbors but not nearly as high in the ranking in order of distance. More recent distance measurements of 12.5–12.6 light years appear to have confirmed this.

Teegarden's Star was discovered on images taken by the Near Earth Asteroid Tracking (NEAT) is a program run by NASA and Jet Propulsion Laboratory to discover near-Earth objects. The NEAT system began observations in December 1995. The principal investigator is Eleanor F. Helin, with co-investigators Steven H. Pravdo and David L. Rabinowitz.
