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, 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 {{Convert|540|ly|pc|abbr=off|lk=on}} 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.
