Gw mau tau MSun = 1.9891×1030 kg dari Béntang. Jelasin dalam bahasa sunda

The masses of other stars can be given in terms of MSun.

Most stars are identified only by catalogue numbers; only a few have names as such.

The names are either traditional names (mostly from Arabic), Flamsteed designations, or Bayer designations. The only body which has been recognized by the scientific community as having competence to name stars or other celestial bodies is the International Astronomical Union (IAU). A number of private companies (e.g. the "International Star Registry") purport to sell names to stars; however, these names are not recognized by the scientific community, nor used by them, and many in the astronomy community view these organizations as frauds preying on péople ignorant of how stars are in fact named.

See star designations for more information on how stars are named. For a list of traditional names, see the list of stars by constellation.
