How to use constellations to find directions _ How to use constellations to find directions

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. There is a bright star seven times away from the end of the spoon, which is the North Star. Directly below it is the north, and clockwise is the 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.
