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. During a search for brown dwarf companions using the Hale telescope in 2004, two candidate companions were identified at angular separations of 5 and 6. However, these were determined to be background stars.
