There is a Sagittarius in the starry sky on a summer night, and there is another Sagittarius here. This is a constellation that should be said more.

Centauri is located in the south of Ophiuchus, between Wolverine and Vela, and can only be seen in several provinces in the south of China on spring nights. There are two bright stars in the constellation. Alpha star was called Nanmener in ancient China, and its apparent magnitude was -0.27m, making it the third brightest star in the whole day. In ancient times, beta star was called Mabelly I, and its apparent magnitude was 0.6 1m, which was the 1 1 bright star in the whole day. The two stars are very close. In ancient China, they were collectively called "South Gate Double Stars", and Zheng He used them to navigate when he went to the Western Ocean in14th century.

Nanmener is a triad star, and its companion star (proxima centauri) 1 1m is only 4.2 light years away from us, which is the closest star to the solar system.
