Aldebaran

What is Aldebaran?

Aldebaran is a K5III star, which indicates that Aldebaran is an orange giant star that has moved off of the main sequence line. The percent of known Aldebaran stars is 0.4%, so they aren't super common, but they definitely aren't uncommon. When Aldebaran fuses, it fuses helium into carbon and oxygen. The mass of Aldebaran is 1.5±0.3, and the radius of Aldebaran is 44.2±0.9. The distance from Earth is 65.3±1.0 lightyears. The color of Aldebaran is orange, the temperature is 3,910 K, and the luminosity is 518±32 L.


Some Myths about Aldebaran

Since Aldebaran is an easily seen and striking star, there are suggestive asterisms that it is a popular subject for ancient and modern myths. In the Mexican culture, for the Seris of Northwestern Mexico, people say that the star provided light for the seven women giving birth.

How do we know about Aldebaran?

In March 509 CE, a lunar occultation of Aldebaran was observed in Athens, Greece. In 1792, William Herschel discovered a faint companion to Aldebaran, with an 11th magnitude at an angular diameter.

Is it a binary, multiple, or single star system?

Aldebaran has five faint stars that are positioned so close that they appear close to Aldebaran. The double stars were given alphabetic secondary star designations more or less in the order of their discovery, and the letter A was reserved for the primary star.

What are the stages of its life?

The first stage in Aldebaran's life was the formation of the star. It then became a Main Sequence star. Next it becomes an orange giant star, which is what it is right now. We know all of this because of William Herschel and William Huggins. They both studied around Aldebaran, and the actual star itself.
