What constellation does Altair belong to?

Cowherd and Weaver Girl is a fairy tale in ancient China, which also comes from two stars. Altair belongs to Eagle and Vega belongs to Lyra. The official name of China Altair is Hegu II, which is combined with other stars to form a constellation, commonly known as Eagle Constellation, and Altair is Eagle Alpha Constellation.

The names and divisions of constellations were introduced from the west. The ancient Greeks imagined it as an eagle flying in the night sky. Altair is the heart of the eagle, and its shoulder pole is the wing of the eagle.

In summer and autumn nights, it is a very famous bright star in the sky, which is silvery white. It is 16.7 light years away from the earth, with a diameter of10.6 times that of the sun, a surface temperature of about 7000℃, a luminous power of 8 times that of the sun, and an apparent star of 0.77, contrary to Vega.

Fairy tales of Vega and Altair

The reason why Vega and Altair are household names in China actually stems from a fairy tale. Legend has it that the granddaughter Weaver of the ancient Emperor of Heaven is very good at weaving, weaving rosy clouds for the sky every day. She hated this boring life, so she secretly went down to earth, married a cowherd in Hexi privately, and lived a life of farming and weaving.

This angered the Emperor of Heaven, took the Weaver Girl back to the Heavenly Palace, and ordered them to separate, allowing them to meet only once a year on the seventh day of the seventh lunar month. Their unswerving love touched magpies, and countless magpies flew in and built a magpie bridge across the Tianhe River with their bodies, so that the cowherd and the weaver girl met on the Tianhe River, which was later the Milky Way.
