Elnath is a blue giant 134 light years from the Earth. It lies at the tip of Taurus' northern 'horn', on the very edge of Taurus' border with Auriga, just one thirtieth of a degree within the boundaries of the Bull. Indeed, as well as its more common Bayer designation of 'Beta Tauri', the star is also occasionally classified as 'Gamma Aurigae'.
