One of the northern constellations. This is a big constellation in the starry sky on a summer night, and it is also one of several big constellations all day.

Although the scope of the five risks is large, it is a pity that the stars in the constellation are not very bright, and they are all composed of 3 stars and 4 stars. 1934, a new star burst was found in the constellation Ursa, and its brightness reached 1, but now it has become a dark star. 1960 and 1963 have new star bursts, but the brightness is not as bright as 1934.

The stars in the moving constellation Ursa major are all in about the same position in the Milky Way, moving in about the same direction at about the same speed, with about the same metal composition, and according to theory, they are also about the same age. These evidences prove to astronomers that they once came from the same source.

Ursa minor is the constellation closest to the north celestial pole. Center position: right ascension 15: 30, declination 75. The area is about 256 square degrees.

Scorpio has no solar terms on the ecliptic, and Ophiuchus has a solar term of heavy snow.

Sagittarius is also a zodiac sign (Sagittarius is also called "Sagittarius" in the zodiac sign), and it can be found south from Altair of Aquila along the Milky Way on summer nights. Because the galactic center is in the direction of Sagittarius, this part of the galaxy is the widest and brightest.

Ophiuchus in the summer night sky, located on the west side of the Milky Way, between Scorpio and Hercules, has a very wide area with sparse stars, which is the location of Ophiuchus and Ophiuchus. Ophiuchus has a billion huge constellations. It is adjacent to Ursa major in the north, Scorpio in the south and Ophiuchus on both sides. The western part of Ophiuchus is near the northern crown and the shepherd, and the eastern part is shorter near the eagle. Ophiuchus is half north of the equator and half south of it. It is the only constellation located in the ecliptic and not belonging to the ecliptic. Ophiuchus and Ophiuchus constitute an image of Ophiuchus holding a giant snake with both hands in the night sky.
