37 Tauri is a single,[9] orange-hued star in the zodiac constellationofTaurus. It can be seen with the naked eye, having an apparent visual magnitude of 4.36.[2] A magnitude 10.01 visual companion has an angular separationof134.30 on a position angle of 138.6°, as of 2003.[10] Based on an annual parallax shiftof17.43±0.21 mas,[1] 37 Tauri is about 187 light years away. It is moving further from the Sun with a heliocentric radial velocity of 9.5 km/s.[6]

This is an evolved K-type giant star with a stellar classification of K0 III-IIIb.[3] At the age of 1.39[5] billion years, it has become a red clump giant, indicating that it is generating energy through helium fusion at its core.[11] The star has around double the mass of the Sun and has expanded to 10[7] times the Sun's radius. It is radiating roughly 60[7] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,732 K.[5]

Chinese astronomy

[edit]

InChinese astronomy, 37 Tauri is called 月, Pinyin: Yuè, meaning Moon, because this star is marking itself and stand alone in Moon asterism, Hairy Head mansion (see : Chinese constellation).[12]
