What is Gemini?

The third sign of the zodiac is Gemini, which is represented by a pair of twins, suggesting his dual personality. Gemini is at dusk in late March and can be seen in the south of the head. The two boys are well side by side, with two brightest stars, that is, their heads. The sun will pass through this constellation.

Extending the connecting line between Orion's beta star and alpha star to the northeast, we can meet two bright stars which are not far apart, among which the brighter one is Gemini's beta star with brightness of 1. 14, etc. The dimmer star is Alpha Gemini with a brightness of 1.97. A series of stars τ, ε, μ starting from α star is almost parallel to another series of stars τ, ζ, γ starting from β star. They are imagined as two friendly brothers-casto and Poole Jocks.

Brother-β star, known as "North River III" in ancient China, is brighter than brother-α star and is the 17th brightest star in the whole day. Brother Alpha, known as "Beihe II" in ancient China, is the first confirmed binary star in the history of astronomy. In fact, it is a "six-star" composed of six stars. Interestingly, my brother Beichuan is also a Liuhe star. These two brothers are really twins. How much they look alike!
