52 Arietis (abbreviated 52 Ari) is a triple star system in the northern constellation of Aries. 52 Arietis is the Flamsteed designation. The combined apparent magnitude is +5.46,[2] which is bright enough to be faintly visible to the naked eye. Based upon an annual parallax shift of 6.05 mas,[1] the system is roughly Script error: No such module "convert". distant from the Earth. The inner pair of this system consist of two nearly identical B-type main sequence stars, each with about five times the mass of the Sun. The tertiary component is a smaller star with 88% of the Sun's mass, and is a common proper motion companion.[5]
