Arcturus and all the other bright stars would have been known to the first astronomers, the Babylonians.
Arcturus is a star located in the constellation of Boötes and is not known to have any planets orbiting around it. It is a red giant star that is relatively close to Earth in astronomical terms, at a distance of about 36.7 light-years. While exoplanets have been discovered around many other stars in our galaxy, none have been confirmed around Arcturus.
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.

No, Arcturus is a red giant star, not a nebula.
Arcturus is the Zenith Star of the Hawaiian Islands
A Voyage to Arcturus was created in 1920.
The Arcturus Star is located in the constellation Bootes.
A Voyage to Arcturus has 303 pages.
1652 Edit : That seems unlikely. Arcturus is one of the brightest stars in the sky and it must have been seen as soon as people looked at the night sky, many thousands of years ago.
