Aldebaran is a red giant, meaning that it is cooler than the Sun with a surface temperature of 3,900 K, but its radius is about 45 times the Sun's, so it is over 400 times as luminous. As a giant star , it has moved off the main sequence on the Hertzsprung–Russell diagram after depleting its supply of hydrogen in the core .
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...

By using this type of diagram, uncovering the themes of a natal chart becomes easier because dispositor trees reveal which planets are superior in power and which planets must obey the ruling planets.
Once considered as having the largest angular diameter of any star in the sky after the Sun, Betelgeuse lost that distinction in 1997 when a group of astronomers measured R Doradus with a diameter of 57.0 ± 0.5 mas, although R Doradus, being much closer to Earth at about 200 ly, has a linear diameter roughly one-third that of Betelgeuse.

Some stars may have been assigned more than one name due to the inaccuracies of traditional star charts. While there is little disagreement on the correspondence between traditional Chinese and Western star names for brighter stars, many asterisms, in particular those originally from Gan De, were created primarily for astrological purposes and ...
Star of David, or Jewish Star, a hexagram symbolizing Israel, Judeans, and/or Jews; properly speaking, this "star" is called the "Shield of David," (Magen David), while the pentagram is the "Star of David." Note that this is a cultural, rather than religious symbol. Star of Lakshmi, a Hindu symbol associated with the goddess Lakshmi
The Sun is the star at the center of the Solar System.It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.
