Which constellation does the Big Dipper belong to?

It belongs to the constellation Ursa major and can be seen all year round in most parts of the northern hemisphere.

This constellation has the most prominent astrology in the whole day, namely the Big Dipper. Many ancient civilizations thought that the astrology of this constellation was a bear, while ancient China thought it was a fight. In the words of the ancients, it is: "The barrel handle points to the east, and the world is spring; Bucket handle guide, the world is summer; Bucket handle refers to the west, and the world is autumn; Bucket handle refers to the north, and it is winter in the world. " .

There was no calendar in ancient times, so people used this method to calculate the four seasons. Of course, due to the rotation of the earth, this phenomenon must be seen after eight o'clock in the evening.

This constellation belongs to seven messier objects in the sky, with many binary stars and variable stars. In Greek mythology, in order to escape Hera's jealousy, Zeus turned the beautiful fairy Crystal Peach into a bear. However, Hera still chased the bear and ordered themis, the goddess of hunting, to shoot the bear. Zeus had to raise the bear to the constellation in the sky.

Observation characteristics—

At different latitudes of the earth, the constellations you can see are different. The constellation Ursa major can be seen all year round in areas above 40 north latitude, that is, north of Beijing and Greece. However, in spring, Ursa major is high in the northern sky, which is the best time to watch its panorama in four seasons.

Ursa major ranks third in the whole sky, second only to Ophiuchus and Virgo. Because of the existence of the Big Dipper (from Alpha Ursa major to η Ursa major, except for Delta Ursa major, the other six are bright stars above second star), Ursa major is probably the most famous constellation in the whole day. The first two stars of the Big Dipper, α and β, are signs for finding the North Star, and the connection between these two stars directly points to the North Pole.
