53 Arietis
star in the constellation Aries
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 and mean apparent magnitude of 6.10, which is near the lower limit for naked eye visibility. Based upon an annual parallax shift of 3.2 mas, the estimated distance to this star is roughly 1,020 light-years (314 parsecs).
The claimed variability of 53 Arietis has not been confirmed.
It is a runaway star with a peculiar velocity of 48.1 km/s relative to its neighbors. The star was ejected from the Orion Nebula some 4–5 million years ago, possibly when an orbiting companion exploded as a supernova. Barnard's Loop is believed to be the remnant of the supernova that launched the star.

Why this record matters
“53 Arietis” is worth following because a concise public description often conceals a longer documentary argument. Here, Arietis, star and constellation provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 21, 2026. The linked authority identifier is Q1133939. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1974.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
