What is the constellation of Ka Rong _ What is the constellation of Ka Rong?

Scorpio is the most prominent of the two constellations. Center position: right ascension 16: 40, declination -36 degrees. Summer appears in the southern sky, and the scorpion's tail points to the southeast, between the snake head, Sagittarius and Libra. Alpha star (Antares) is a red star with a magnitude of 1. The open clusters M6 and M7 are visible to the naked eye. There are 22 stars in the constellation that are brighter than 4.

The eighth house of Scorpio. The longitude of the meridian varies from 2 10 degrees to 240 degrees. The sun comes to this house every year around1October 23rd, 10. The solar term at that time was the first frost.

At eight or nine o'clock in the summer evening, there is a bright star in the south, which is not very high from the horizon. It is Scorpio Alpha (Antares).

Scorpio is the most conspicuous constellation in summer. There are many bright stars in it, and there are more than 20 brighter than 4m. Scorpio is big and bright, with many stars, which can be said to be the representative of the summer night constellation. In addition, it is also a zodiac, so it is particularly eye-catching. However, Scorpio only occupies a short range of 7 on the ecliptic, which is the shortest ecliptic among 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 placed in the center of 28 nights, which was called "Antares". You see, astronomers in the East and the West happen to coincide.

M7 open cluster M7 is one of the most famous open clusters in the sky. This cluster has many bright blue stars. At night, we can see it from the tail of Scorpio with the naked eye. M7 is about 1000 light years away from us, and consists of about1000 stars, with an age of about 200 million years and a size of about 25 light years. The above color photo was recently taken by the Kitt Peak National Observatory in Arizona, USA, and it is part of the Advanced Observer Program. As early as ancient times, people began to know about the M7 open cluster, which Ptolemy observed in 130. You can also see the dark dust clouds at the bottom of the constellation frame and millions of stars in the center of the Milky Way that have nothing to do with clusters.
