If we connect the celestial star's bright stars together, we get a big cross. It is opposite to the South Order, so it is called "Northern Cross" . Greek astronomers pool the "Northern Cross" with the surrounding swan-like stars, the Swan's tail is a first-class star - Tian Tan 4. Not far from Tianjin 4 to the East And another famous star, Swan 61, is about 11 light-years away. In addition to the Sun, Swan 61 is the 13th planet closest to us. Crystal eyes can see it in the night sky.

Greek mythology said that Jeus loved Queen Sparta as Leda, but feared that his wife would be jealous, he turned Leda into a swan to cheer him up early, giving birth to two children (Gemini). Later Jeus celebrates this love as a constellation of the Swans.

Observe the constellation of swans and dive very interesting . Swans grow from the Northeast. It was like a Swan tilting its wings. When reaching the zenith, the head turns south, slightly shifting to the West. When it moved to the Northwest, the head wished down, the tail perked up and finally dove under the horizon.
