Taurus, in astronomy, zodiacal constellation lying in the northern sky between Aries and Gemini, between about 3 hours 30 minutes and 6 hours right ascension and between 0° and 30° north declination. It can be seen in the evening sky in the winter in the Northern Hemisphere and in the summer in the Southern Hemisphere.

  • Brightest star: Aldebaran, red giant, magnitude 0.85, 65 light-years from Earth
  • Prominent objects: Hyades, star cluster, 150 light-years from Earth; Pleiades, star cluster, 440 light-years from Earth; Crab Nebula (M1), supernova remnant, 6,500 light-years from Earth

Taurus’s brightest star, Aldebaran (Arabic for “the follower”; also called Alpha Tauri), is the 14th brightest star in the sky, with a magnitude of 0.85. The constellation is easily visible with Aldebaran and the Hyades star cluster forming a bright V shape. The constellation also contains the conspicuous Pleiades, a compact cluster of bright stars, as well as the Crab Nebula (M1), a remnant of the supernova whose explosion was visible during the day in 1054 ce.

Taurus’s association with a bull arose in Babylon in the late second millennium bce when the constellation was identified with the storm god Adad, who was sometimes depicted as riding on a bull. The constellations of ancient Mesopotamia were adopted by the Greeks, and Taurus became identified with the myth of Zeus taking the form of a bull to carry off the princess Europa.
