What do you think of the upper constellation of the constellation?

When winter comes and summer goes, the stars move. This shows that with the change of seasons, the starry sky in the four seasons is also changing. Let's take Beijing as an example and look at the starry sky in four seasons.

spring

1/2 Step by step reading

The main constellations of the starry sky in spring are:

Ursa major, Ursa minor, Leo, Capricorn, Canis major, Virgo and Ursa major.

2/2

Ursa major and Ursa minor.

Big Dipper: A part of Ursa Major, which consists of five bright second-class stars and two third-class stars. A spoon-shaped Big Dipper is equivalent to the waist-to-tail part of Ursa Major, in which four stars form a bucket spoon and the other three stars form the bucket handle.

summer

1/2

It is best to learn to recognize the summer constellation from Scorpio, which shines near the southern horizon.

2/2

Scorpio is a powerful constellation, consisting of 1 fiery red star, 3 second-class stars and 10 third-class stars.

To the east of Scorpio is Sagittarius, and in the eastern half of Sagittarius, there are six stars called Nandou.

At this time, the Big Dipper is in the northwest sky. After finding the constellation Capricorn, to the east, almost to the zenith, there is a semicircle constellation called Beiguan, just like a jewel-encrusted crown, where a large number of galaxies gather.

autumn

1/2

Learning to recognize the constellation of autumn night, it is best to start with Cassiopeia shining in the northeast galaxy.

There are many princes and nobles in the autumn night sky: fairy king, fairy queen, fairy, fairy, flying horse and whale.

2/2

Cassiopeia is composed of three second-class stars and two third-class stars, showing a W shape. Because of its unique shape, it is easy to recognize, and it will never be forgotten after the first meeting.

After that, you can easily find the North Star.

Methods: Connect the two stars on both sides of W respectively, extend the connecting line to the intersection point, then connect it with the star in the center of W with the lead of the intersection point A, and extend it forward about 5 times to get the position of the North Pole star.

winter

1/2

Although it is cold in winter, the starry sky is magnificent, and the constellations compete with each other, as if holding a hero's party in the starry world. Orion is the center of the winter sky.

So we'd better start with Orion.

2/2

You can see three bright stars in neat rows at night. There are four bright stars around Samsung and Samsung form a rectangle. This is Orion, and Samsung is Orion's belt.

Sirius: If you want to extend the three-star connection to the lower left, you can meet the brightest star in the whole day.
