What are the positions and shapes of the twelve constellations in the sky?

Leo is the constellation of spring, bright and easy to find. Search in the southern sky at eight or nine o'clock in the evening of April. The first half of Leo consists of six stars, like a question mark written backwards, and the tail is a triangle, which together is the main body of Leo.

The center of Aries is at 2: 40 right ascension and 2 1 declination. Alpha star is a second-class star, and there are five brighter than the fourth-class star.

Every year from June 5438 to mid-February at 8: 00, Aries is above our heads. This is a very dark small constellation, in which only the next 2.3m α star and 2.7m β star are slightly meaningful.

The four stars Pegasus and Andromeda in the autumn sky make up a big box. Draw a straight line from the two stars in the north of the box and extend it to the east for one and a half times, and you can see Aries.

It is the zodiac, so its position in astronomy is still very important.

Every September, near the southern horizon, facing Scorpio is Sagittarius. Sagittarius's sword always points to Scorpio's heart. The symbol of Sagittarius is a flying sword, representing freedom and speed.
