If you get lost at night, how can you tell the direction with the constellation?

Observe the sky: The most common way to observe the sky is to observe Polaris. At night, in the dark night sky, we always find the Beidou constellation shaped like a spoon. Seven times from the end of the spoon, there is a bright star, the Polaris, which is directly below the north and clockwise is east, south and west.

Sun and Moon: The sun rises in the east and sets in the west. Observing the sunrise and sunset can generally show a general direction. You can also use the following methods to measure: erect a straight stick (1 meter high or above) on the flat ground, first make a mark on the top of the shadow of the straight stick (such as putting a stone), and the shadow of the straight stick will move with the movement of the sun. After 65,438+00-60 minutes, make another mark above the shadow of the stick, and draw a straight line between the two marks, which is vertical in the middle.
