Capella is a very big double star, each star being about 10 times the mass of our sun. But Aldeberan is a true "Red Giant" being more than 40 times the diameter of our sun. In this comparison, Aldeberan is much the larger of the two.
Betelgeuse is the brighter star compared to Aldebaran. It is a red supergiant star in the constellation Orion and is one of the brightest stars visible in the night sky. Aldebaran is an orange giant star in the constellation Taurus and is not as bright as Betelgeuse.
Aldebaran, the brightest star in the constellation Taurus, has a distinctive orange hue. This color is indicative of its classification as a K5 III giant star, which means it has a surface temperature of about 4,000 Kelvin. Its warm color results from the cooler temperature compared to hotter stars, making it appear orange to the naked eye.
The distance between our solar system and Aldeberan is listed as 65.1 light-years.
