Gamma Arietis

Gamma Arietis is a binary or possibly trinary star system in the northern constellation of Aries. Its name is a Bayer designation that is Latinized from γ Arietis, and abbreviated Gamma Ari or γ Ari. This system is called "The First Star in Aries" as having been at one time the nearest visible star to the equinoctial point. The combined apparent visual magnitude of the stars is 3.86, which is readily visible to the naked eye and makes this the fourth-brightest member of Aries. Based upon parallax measurements, the distance to Gamma Arietis from the Sun is approximately 166 light-years (51 parsecs). The two components are designated γ1 Arietis or Gamma Arietis B and γ2 Arietis or Gamma Arietis A. The latter is formally named Mesarthim, pronounced , the traditional name for the Gamma Arietis system. γ1 Arietis may itself be a spectroscopic binary with a low mass companion.
