Vega related introduction:

Vega is an ellipsoid star with a pale pink north pole and a blue equator. Because of its fast rotation speed (Vega rotates once every 12.5 hours), the whole star is flat, and the equatorial diameter ratio is 23%. Next to Vega, four stars form a small diamond.

Legend has it that this small diamond is a shuttle used by the weaver girl to weave cloth. While knitting, the Weaver Girl looked up at the Cowherd (Hegu II) and her two sons (Hegu I and Hegu III) on the east bank of the Milky Way with deep affection. Vega, Tsukuya II (Altair) in the eagle and Tianjin IV in Cygnus form the famous "Summer Triangle". If you think of it as a right triangle, Vega is a star that forms a right angle.
