HD 172051 is a main sequence dwarf star in the
constellation Sagittarius.

It is located about 42 light years from the Sun and is considered a solar analog. It is similar in mass to the Sun, although it is cooler and has a lower luminosity. Due to this similarity, HD 172051 has been selected as an early target star for both the Terrestrial Planet Finder and Darwin missions, which seek to find an Earth-like extrasolar planet.
