Astronomers call it α Tau — the Bayer designation, which reads as a Greek letter ranking its brightness within its constellation. Aldebaran is the name people actually use.
Aldebaran shines at magnitude 0.85, making it a first-magnitude star, among the brightest few dozen visible. Its B−V colour index of 1.54 makes it orange-red to the eye, corresponding to a surface temperature of under 4,000 K.
It sits at right ascension 4.60 hours and declination +16.5°. It straddles the celestial equator, so it is visible from essentially anywhere on Earth at the right time of year.
