How to find Cancer from the night sky?

It depends on where you observe it. Internationally, the starry sky is divided into 88 constellations. Cancer looks at the night sky in the north (according to the law of going up, down, south, left, west, right and east): in the middle is the North Star of Ursa minor (including the Big Dipper), all the way to the southeast is Tmall, and then to the southeast is Cancer, which is Y-shaped. Then Ophiuchus.

Look at the southern night sky: South Pole in the middle, T-shaped. At this time, cancer is invisible.
