What is the numeric code of Cowherd and Weaver Girl?

Many people have seen a cold joke before, saying that the Cowherd and the Weaver Girl are immortals, which means that they only admire Yuanyang but not immortals. But what is the real Cowherd and Weaver Girl constellation like? Then please read on.

Altair:

Altair is somewhat similar to the sun, because it can glow by itself. At the same time, the name of Altair is called "Hegu II" in China, because Altair is a constellation composed of several stars around it, also known as Eagle constellation.

Vega:

Vega, like Altair, is also a constellation that combines with other stars around it. In China, it is called "Weaver Girl 1", but the name of this constellation is called "Qin Tian Constellation".

Although we all know a legend, every year on July 7th, thousands of magpies meet the Cowherd and the Weaver Girl on the bridge. The older generation also told us that you can hear the Cowherd and the Weaver Girl talking under the vine, but do you know how far these two constellations are?

Altair and Vega are far from us. The earth length of Altair is about 16 light years, while Vega is 27 light years. But Altair and Vega are separated by 16 light years, so they can be regarded as the crystallization of two constellations representing love. No matter how rough it is, it is impossible to stop them from meeting. Even if it is a big difficulty, both sides will overcome it.

Thus, China's Tanabata was formed. Every couple wants to have a love affair like a cowherd and a weaver girl. Although bumpy but in love, although difficult, we must be together.
