Scorpio in astronomy. How many stars are there in Scorpio and how far is it from the earth? Tell us about it in detail.

Scorpio is the most prominent constellation in the zodiac, located in the southern hemisphere, between Libra in the west and Sagittarius in the east. It is a big constellation near the center of the Milky Way. It is also a famous constellation in the northern hemisphere in summer.

Scorpio center: right ascension 16: 40, declination -36 degrees, with an area of 496.78 square degrees. Summer appears in the southern sky, and the scorpion tail points to the southeast. Alpha star (Antares) is a red star with a magnitude of 1. The open clusters M6 and M7 are visible to the naked eye, and 22 stars in the constellation are brighter than 4 stars.

Scorpio is the most conspicuous constellation in summer, and it is also the representative of summer night constellation. In addition, it is also a zodiac, so it is particularly eye-catching. Scorpio, on the other hand, only occupies a short range of 7 on the ecliptic, and only rubs one side on the ecliptic, which is the shortest of the twelve constellations.

Scorpio is immersed in the vast galaxy from alpha star to long scorpion tail. Alpha is located in the scorpion's chest, so the west calls it "the heart of Scorpio". Interestingly, in ancient China, the alpha star of Scorpio was just placed in the constellation of Twenty-eight Nights, which was called "Antares", and this star was also regarded as a big scorpion.

In astronomy, we can't say which constellation is far from us. Because the so-called constellations are all the projections of stars in a certain area in the sky on the celestial sphere. For us, any constellation is the same distance from us. But the actual distance between each star and us is far and near.
