Rho3 Arietis (Rho3 Ari, ρ3 Arietis, ρ3 Ari) is the Bayer designation for a star in the northern constellation of Aries. It is faintly visible to the naked eye with an apparent visual magnitude of 5.63. [2] Based upon an annual parallax shift of 28.29 mas, [1] this star is located at a distance of approximately 115 light-years (35 parsecs) from Earth.
This is an astrometric binary system. [7] The visible component is an F-type main sequence star with a stellar classification of F6 V. [3] It is around 2.4 billion years old [4] and has a high abundance of elements other than hydrogen and helium when compared to the Sun. [5]
This star, along with δ Ari, ε Ari, ζ Ari, and π Ari, were Al Bīrūnī's Al Buṭain (ألبطين), the dual of Al Baṭn, the Belly. [8] According to the catalogue of stars in the Technical Memorandum 33-507 - A Reduced Star Catalog Containing 537 Named Stars, Al Buṭain were the title for five stars : δ Ari as Botein, π Ari as Al Buṭain I, ρ3 Ari as Al Buṭain II, ε Ari as Al Buṭain III dan ζ Ari as Al Buṭain IV [9]
