1what constellation was born on August 5, 995?

Leo, Leo's Five Emperors (Beta Star), Capricorn's arcturus and Virgo make up the famous "Spring Triangle" in the spring sky.

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.

In the spring night, we found the beta star of Leo through the spring triangle, that is, after the five emperors sat down, a big star to the east of it was all Leo. 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 is called Xuanyuan XIV in China, and its apparent magnitude is1.35m. It is located in the center of Leo, which is also a point of the question mark written later. It is the brightest star in Leo and the 2nd1brightest star in 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, which is about 90 degrees away from the four bright stars Taurus, Scorpio Antares and Nanyu's Beiluoshimen. They are 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, there are 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.

Leonid meteor shower was still flourishing in 1866, but it was much less in 1899, and only a few were seen in 1932 and 1965. By 1998 and 1999, the Leonid meteor shower was magnificent again and reached its peak.

Leo is in the middle of the day before dawn in mid-June 165438+ 10 every year. If you want to watch the meteor shower, you must get up early!
