52 Arietis is the Flamsteed designation for a triple star system in the northern constellation of Aries. The combined apparent magnitude is +5.46 which is bright enough to be faintly visible to the naked eye. Based upon an annual parallax shift of 6.05 mas the system is roughly 540 light-years (170 parsecs) 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.
