53 Arietis (abbreviated 53 Ari) is a variable star in the northern constellation of Aries. 53 Arietis is the Flamsteed designation; it also bears the variable star designation UW Arietis. It is a B-type main sequence star with a stellar classification of B1.5 V[3] and mean apparent magnitude of 6.10,[2] which is near the lower limit for naked eye visibility. Based upon an annual parallax shift of Script error: No such module "val"., the estimated distance to this star is roughly Script error: No such module "convert"..
The claimed variability of 53 Arietis has not been confirmed.[4][9] [10] It is a runaway star with a peculiar velocity of 48.1 km/s relative to its neighbors.[6] The star was ejected from the Orion nebula some 4–5 million years ago, possibly when an orbiting companion exploded as a supernova.[11] Barnard's Loop is believed to be the remnant of the supernova that launched the star.
