Arcturus, a red giant star, is expected to exhaust its nuclear fuel in the next few million years and eventually shed its outer layers to form a planetary nebula. It will then collapse into a white dwarf, where it will slowly cool over billions of years.
Vega appears brighter than Arcturus in the night sky because it is closer to Earth, being only about 25 light-years away compared to Arcturus which is around 37 light-years away. Additionally, Vega is a hotter and more luminous star compared to Arcturus, contributing to its perceived brightness.
Arcturus has an absolute magnitude of -0.29 and an apparent magnitude of -0.04
No. Arcturus is believed to be a single star.
Arcturus is not a double star; it is classified as a single giant star, specifically a red giant of spectral type K1. However, it does have a very faint companion that is often not considered in the context of double stars due to its low brightness. This companion is not a part of Arcturus's primary system but is instead a background star. Therefore, Arcturus is primarily known as a solitary star.
