Greetings, I think in Stellarium is not correct Arcturus star description, at first Arcturus isn’t double star but red giant star, and I think visual magnitude isn’t correct too because Stellarium says magnitude −0,15 but I found magnitude − 0,05. arcturus

Thank you for answer.

Arcturus may have a binary companion. See same source. Many sources provide different values for mag.

Oops, I'm sorry, I overlooked information about binary companion.
