It may be the coolest star, but it is not the biggest star known to man.
The biggest star known to man is called VY Canis Majoris. It's almost bigger than our GALAXY, which is VERY big.
The Arcturus Star is located in the constellation Bootes.
5 trillion years old
Arcturus was not discovered by one specific individual. It has been known and observed for thousands of years by various ancient civilizations. It is one of the brightest stars in the night sky and has been used as a navigational reference point for sailors and astronomers throughout history.
No. Red stars are the coolest. Blue stars are the hottest.
The coolest stars are red in color. They are classified as red dwarfs and have surface temperatures ranging from about 2,500 to 3,500 degrees Celsius.
I don't know about pointing at two stars, but the last two stars in the big dipper's handle point to Arcturus, one of the brightest stars in the sky. Arcturus is in the constellation of Bootes, the Herdsman.

No, Arcturus is not a planet. It is a red giant star located in the constellation of Boötes. It is one of the brightest stars in the night sky and is visible to the naked eye.
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.
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.
