A very faint star of the type known as a red
dwarf. Only recently discovered, this star was initially thought to be just 7.8
light years from the Solar System, making it the
third nearest stellar system to the Sun; later measurements suggest that it is somewhat further away than this initial estimate, and that Teegarden's Star actually lies 12.5
light years or more from the Sun. This
faint red dwarf
star, one of several in relatively close proximity to the Solar System whose low Luminosity makes them difficult to detect.
