What are the stars on the head of the constellation Taurus?

The three brightest stars on the bull's head are its eye and two horns (seen in profile)



Aldebaran, Alpha Tauri, (HD 29139) known as the eye of the bull is an orange giant and the brightest star in the constellation. It has exhausted its hydrogen fuel and is now fusing helium. It has a dim red dwarf companion:



Apparent magnitude (V) +0.85 / +13.50

Spectral type K5III / M2V

Distance 65 卤 1 light years



Elnath, beta Tauri, (HD 35497) is a magnesium-rich star evolving into an orange giant and one of the horns of the bull. The traditional name is from the Arabic 丕賱賳胤丨 an-na牛魔 "the butting" (i.e., with the bull's horns).



Because it is on the boundary of Taurus with Auriga, it also has the redundant Bayer designation Gamma Aurigae (纬 Aur), which is today very rarely used.



Apparent magnitude +1.65

Spectral type B7 III

Distance 131 卤 5 light years



Zeta Tauri, HD 37202 is the other horn of the bull. Known to the ancient Babylonians as Shurnarkabti-sha-shutu, meaning "the star in the bull towards the south," Zeta Tauri is among the most prominent of the stars in well-known constellation figures, representing one of the celestial bull's protruding horns.



Defining mid-third magnitude (3.00), Zeta Tauri is a brilliant hot blue-white B-type giant star approximately 417 light years from Earth. It is classified as a Gamma Cassiopeiae type variable star. Its brightness varies from magnitude +2.88 to +3.17 due to both its intrinsic variablility, and also because it is an eclipsing binary.



The two components of the binary system are separated by approximately one Astronomical Unit and complete an orbit once every 133 days. Its much lower mass companion star is a yellow G-type star, which has a magnitude of +5.2. A 9 solar mass star around 25 million years old, Zeta Tauri is now evolving, and is close to giving up core hydrogen fusion, if it has not done so already.



It radiates the light of approximately 5,700 of our own sun from a surface heated to 22,000 kelvins.
