UX Arietis is a variable star of the RS CVn type, located in the northern zodiacal constellation of Aries. Based upon parallax measurements from the Hipparcos satellite, it is roughly 168 light years away.[1] The variability of the star is believed due to a combination of cool star spots and warm flares, set against the baseline quiescent temperature of the stellar atmosphere. The variability appears to be cyclical with a period of 8−9 years.[4]
