Bear in the constellation 12 _ Is there a bear in the twelve constellations?

Ursa minor is the nearest Polaris to the North Pole. In fact, the Big Dipper is part of the constellation Ursa Major. Like Ursa major, Ursa minor's tail can also be regarded as the handle of a bucket (or spoon). Ptolemy and modern 88 constellations both include Ursa minor. Ursa minor marks the position of the north celestial pole, and Alpha Ursa minor, the brightest star in the constellation, is the current Polaris. Polaris is a star in Ursa minor, and it is also located in the tail position.

Never confuse Ursa minor with Ursa major. Ursa minor looks only half as big as Ursa major. In fact, the structure of Ursa major is more complicated. Some people simply call Ursa major the Big Dipper and Ursa minor the Little Bear.

Alpha Ursa belongs to Polaris.

But Polaris is not specifically Alpha Ursa. It's like Coca-Cola belongs to Coca-Cola, but Coca-Cola doesn't necessarily mean Coca-Cola.

Dog Chen Yi (α Ursa minor) is the brightest star in this constellation. It is a yellow-white Supergiant star and the brightest Cepheid variable in the night sky. Its apparent magnitude ranges from 1.97 to 2.00.

Polaris II (beta Ursa minor) is in the late stage of its life. It has expanded and cooled into an orange giant with an apparent magnitude of 2.08, only a little darker than Gou Chen. Arctic II and Arctic I (Ursa minor γ) were once called "the guardian stars of Polaris".
