Is arcturus a double 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.
