BWM 20 is associated with the group of stars in Aquarius known as M73, which was originally catalogued as an open cluster, but is now thought to be an asterism of unrelated stars. The main body of M73 is formed by the four brighter stars seen to the east (left) here, with BWM 20 being a western outlier. Parallax data for BWM 20 implies that it is considerably more distant then the more prominent stars of the asterism. Imagery provided by Aladin sky atlas

* The spectral classification for this star is not directly recorded. The 'yellow dwarf' classification given here is inferred from the star's established colour index and luminosity data, and may not be precise.
