Kochab. Kochab, designated as Beta Ursae Minoris, is the brightest star in the bowl of the Little Dipper asterism, and the second-brightest star in the constellation of Ursa Minor.
What is the Little Dipper’s real name?
Ursa Minor
Recently I wrote about the constellation Ursa Major, the Big Bear, so this week I’ll take a look at Ursa Minor, the Little Bear. The seven main stars that form Ursa Minor are also known as the Little Dipper, whereas the seven brightest stars of Ursa Major constitute the famous pattern known as the Big Dipper.
