Aldebaran is the brightest star in the constellation Taurus, with the Bayer designation α Tauri, latinised as Alpha Tauri. It has the Flamsteed designation 87 Tauri as the 87th star in the constellation of approximately 7th magnitude or brighter, ordered by right ascension.
Bayer assigned a lowercase Greek letter (alpha (α), beta (β), gamma (γ), etc.) or a Latin letter (A, b, c, etc.) to each star he catalogued, combined with the Latin name of the star's parent constellation in genitive (possessive) form. The constellation name is frequently abbreviated to a standard three-letter form.
It includes a naked eye double star, Theta Tauri (the proper name of Theta 2 Tauri is Chamukuy), [19] with a separation of 5.6 arcminutes. [20] HP Tauri, a T Tauri variable star and triple system. In the northwestern quadrant of the Taurus constellation lie the Pleiades , one of the best known open clusters, easily visible to the naked eye.
