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.
Roughly half of all stars in the galaxy are estimated to be part of binary or multiple star systems. This means approximately 50% of stars are binary stars.
Hmm. Let's have a look out side. How many Suns do I see? One. Our Solar System is not part of a binary star system, otherwise you'd see two Suns in the sky.

No - it is a single star system
No, our Sun is not part of a binary system.
No, as a binary system is two stars, one circling around the other

Part of a binary star system.
Yes, all binary stars are part of star systems. Binary stars are pairs of stars that orbit around a common center of mass due to their gravitational attraction to each other. While they may be the only two stars in their system, they are still considered part of a larger system.
The Sun is not part of a binary system because it formed from a collapsing cloud of gas and dust in the early solar system, without a companion star. Binary systems typically form from the fragmentation of interstellar gas clouds, resulting in two stars that orbit around a common center of mass.

A star that is gravitationally bound to another star can either be part of a binary star system, where two stars orbit around a common center of mass, or be part of a star cluster, where multiple stars are held together by gravitational forces within a common region of space.
There may already be one. The nearest black hole known is a few thousand light years away, but it is easier to find black hole if they are part of a close binary system. A single star converting to a black hole, or a part of a binary system where the components are not very near, would be difficult to detect.There may already be one.

A star that is not part of a binary (or trinary) star system. The Sun is also a solitary star.
according to latest astronomical research and nasa sources, our sun just may have a brown dwarf companion.
