Where is the Polaris in the night sky?

In the northern night sky (northern hemisphere), it is easy to find the well-known Big Dipper (Ursa Major), which is shaped like a spoon. March to May is spring every year. Take the starry sky seen at eight or nine o'clock in the middle of April as an example. Then you will see the Big Dipper bucket handle pointing east. June to August is summer every year. Take the starry sky seen at eight or nine o'clock in mid-July as an example. At this time, the bucket handle of the Big Dipper points to the south. September ~ 165438+ 10 is autumn every year. Take the starry sky seen at eight or nine o'clock in the middle of 65438+ 10 as an example. At this time, the Big Dipper has come to the north at low altitude. Generally speaking, it is not easy to see the Big Dipper in the area south of the Yangtze River valley in China at this time. Every year from February 65438 to February of the following year is winter. Take the starry sky seen at eight or nine o'clock in the middle of June 65438 as an example. Although the weather is cold in winter, the bright stars in the starry sky in winter night are more magnificent than the other three seasons. At this time, the Big Dipper has reached the northeast sky, and bucket handle points to the north. The center of the winter night sky is Orion, which appears in the southern sky. Ancient Greek mythology imagined Orion as a brave hunter.

The names of these seven bright stars are: Shu Tian, Tian Xuan, Tianji, Tian Quan, Yuheng, Kaiyang and Yaoguang. The first four stars are called "Dou Kui" or "Xuan Ji"; The last three stars are called "bucket" and "bucket handle".
