A little information about 88 constellations:

Andromeda

Andromeda has already mentioned it when talking about the autumn quadrangle (see the constellation introduction of Pegasus). The alpha star that constitutes this quadrilateral is the brightest star in Andromeda, which extends northeast from the diagonal line from Alpha Pegasus to Alpha Andromeda in the quadrilateral, and the three bright stars of Andromeda (except for the delta of 3m, the other two are 2m stars) are almost all on this extension line. Further on, you will meet the great spirit of Perseus. Daling V, Perseus α and Andromeda γ form a right triangle.

This Andromeda gamma star is a binary star, in which the main star is an orange star with a length of 2.3m and the companion star is a * * star with a length of 5.1m.. Interestingly, this companion star is a "chameleon", which changes from * * and gold to orange and blue, just like a clever magician.

Andromeda's most famous celestial body is probably the Big Nebula. Near Andromeda υ, on a clear moonless night, we can see a small blue and white cloud, which is the Andromeda Nebula. This nebula was discovered by astronomers as early as 16 12, but it was not until the 1920s that American astronomer Hubble made it clear that it was completely different from the nebula in Sagittarius. It is a large galaxy 2.2 million light years away from us, so its correct name should be "Andromeda Extragalactic Galaxy".

Andromeda, an extragalactic galaxy, has a diameter of 65.438+0.7 billion light years and contains more than 300 billion stars. Much like our Milky Way, it is also a vortex, and there are also many variable stars, clusters and nebulae. Interestingly, there are two small galaxies nearby, which together form a triple galaxy.

Le Signe du Lion

Once I mentioned Leo when I introduced Capricorn and Virgo in the spring night sky. The constellations of beta star in Leo, arcturus in Capricorn and Virgo form an important "Spring Triangle" in spring night.

Leo is also the zodiac sign. Due to precession, the apparent motion of the sun just passed Leo in June every year more than 4,000 years ago. It's June, and the obvious movement of the sun has reached between Taurus and Gemini. At that time, people in the ancient Persian Gulf country of Chaldea thought that the sun got a lot of heat from Leo, so the weather became hot. The ancient Egyptians felt the same way, because at this time of year, many lions moved to the Nile Valley for the summer.

Ancient Egypt worshipped Leo very much. It is said that the famous Sphinx is shaped by the body of a lion and the head of a maid. The star of Leo was also highly valued in ancient China, and was called the God of the Yellow Emperor and Xuanyuan.

After we found the beta star of Leo through the spring triangle on a spring night, a big star to its east was all Leo's. In Leo, delta, theta and beta stars form a remarkable triangle, which is the lion's back and tail. These six stars from ε to α form the shape of a sickle, which is also like a reverse question mark. This is the lion's head. When the Polaris connecting the constellation Ursa major (that is, the two stars in the spoon mouth) extends in the opposite direction to Polaris, you can find it. Alpha star is called Xuanyuan XIV in China, and its apparent magnitude is1.35m. It is the brightest star in Leo, and it is the 2nd1in the whole day. It forms an isosceles triangle with arcturus and arcturus, and can be found by extending the δ and γ stars of Ursa Major ten times. In ancient times, navigators often used it to determine the position of ships in the sea, so Alpha Leo was awarded the title of "one of the nine navigation planets".

Leo's Xuanyuan XIV is located near the ecliptic. It has four bright stars, which are about 90 degrees apart from each other on the celestial sphere, just one in each season. Together with Pisces in Taurus, Antares in Scorpio and Nanluoshimen, it is also located near the ecliptic. They are collectively called the "Four Heavenly Kings" of the Zodiac.

Every year in June165438+1mid-October, especially in the nights of June 14 and June 15, a large number of meteors will appear near ζ star with question marks written on Leo. This is the famous Leonid meteor shower. It peaks every 33 years. As early as 93 1 year, it was recorded in China in the Five Dynasties. At the peak of 1833, meteors exploded near zeta star like fireworks, with tens of thousands of them every hour. Therefore, the next night, a farmer hurried outside to see if all the stars in the sky had fallen out. Can you explain that the sun belongs to Leo? -American police)

Summary: Does the sun belong to Leo in 12 and 88 constellations? I don't know much about constellations, so I'd better ask an expert.
