41 Arietis or c Arietis is a star in the constellation Aries. It has the traditional name Bharani, named after the Hindu astrological mansion. It does not possess a Greek letter Bayer designation, since this star was once part of the now-obsolete constellation Musca Borealis, but is sometimes designated c Arietis.
In Chinese, 胃宿 (Wèi Su), meaning Stomach (asterism), refers to an asterism consisting of 41 Arietis, 35 Arietis and 39 Arietis.[1] Consequently, 41 Arietis itself is known as 胃宿三 (Wèi Su sān, English: the Third Star of Stomach.)[2]
41 Arietis belongs to the spectral class B8Vn, and has a stellar magnitude of +3.61. It is 160 light-years from Earth.
