Which constellation is the first bright star of Altair? What's the point?

Altair and Vega are famous stars, which can be easily observed in summer and autumn. They are high in the sky. They are charming stars in the summer night sky. Many people must be curious about Altair. In fact, this star is hotter than the sun, younger than the sun, and twice the diameter of the sun. So which constellation is Altair?

Tianying constellation

Altair is the star of Aquila, which is a very famous constellation. Many times, I have heard of this constellation. Hegu II is the alpha star of Aquila, commonly known as Altair. It is a very famous bright star in the sky in summer and autumn, and it is silvery white. It is 0/6.7 light years away from the Earth/kloc-0, its diameter is 0/0.6 times that of the sun, its surface temperature is about 7000℃, its luminous power is 8 times greater than that of the sun, and its visual magnitude is 0.77. It faces Vega across the Milky Way. According to an ancient legend, the Cowherd and the Weaver Girl met at the Magpie Bridge on July 7th. In fact, the Cowherd and the Weaver Girl are 16 light years apart. It's a long distance, even with the fastest tools, it's hard to meet each other, so you can't trust ancient legends too much, just listen to stories.

source

I'm afraid people often hear that cowherd and weaver girl. It is because of this allusion that people are interested in this star. The two darker stars on both sides of Cowherd are Cowherd's son and daughter-Hegu No.1 and Hegu No.3.. Legend has it that the cowherd and a daughter are chasing the weaver girl on the pole. As early as the Han Dynasty, the Book of Rites said in Zheng Xiao: "The weaver girl travels eastward in the middle of the month, and the stars also cover the story." That is to say, at least in the Han Dynasty, people have noticed the running law of Vega in the sky, especially in July. The origin of this legend may be in the earliest Eastern Han Dynasty. It is said that it is a very sad love story that the Cowherd and the Weaver Girl meet in Tianhe on the seventh day of July.

meaning

Many allusions have mentioned the problem of the Cowherd and the Weaver Maid, and people put forward this legend with relish, including other meaning. According to the Chronicle of Jingchu in Zonggu, Southern Dynasties, at that time, in Jianghan area, on the evening of the seventh day of July, women in every household had to tie colored silk thread with very thin needles, and some people used gold, silver and copper as needles to weave melons and fruits in the yard. If spiders weave webs on melons and fruits, it is considered as a sign of the arrival of Vega God. That is to say, on the night of July 7, there is not only the significance of meeting the Cowherd and the Weaver Girl, but also the significance of praying for wisdom from the Vega God. As the textile goddess in folklore, Vega symbolizes the diligence and wisdom of ancient working women. I hope that through this activity, I can get wisdom and get God's blessing.
