53 Arietis is a variable star of Beta Cephei type, alternatively denoted "UW Arietis", in the constellation Aries. Its mean apparent magnitude is 6.13 and its spectral type is O or early B. It is a runaway star, thought to have been produced as a consequence of one of a pair of binary stars colliding. Tracing its motion back shows it was ejected from the Trapezium cluster in the Orion nebula approximately two million years ago.
