Besides Polaris and Big Dipper, what other constellations can tell the direction?

First, determine whether you are in the southern hemisphere or the northern hemisphere. If you are in the northern hemisphere, you can determine the north according to the Polaris. The way to determine the position of Polaris is (first find Ursa major, also called the Big Dipper). Taking the two stars of the spoon handle as the standard length, the "standard length" measured five times in the direction pointed by the spoon handle is the accurate position of the Polaris.

If you are in the southern hemisphere, you should look for the Southern Cross.

It is easy to find a cross consisting of five stars, and you can basically find it by turning around. The three stars in the middle point to the south, but they are not quite right.

Aim for the North Star. First, find the spoon-shaped Big Dipper, and extend the interval between the two stars on the spoon C by five times. Then, you can find the Polaris on this straight line. The direction of Polaris is due north.

The Southern Cross constellation, near the south celestial pole, is composed of four bright stars, shaped like a cross. Known as the cross star in China, it is the main basis for determining the position in the southern hemisphere at night. In the area south of 23 north latitude, the southern cross constellation can be used to determine the orientation in the first half of the year. The Southern Cross constellations α and β are famous first-class bright stars in the southern sky, and γ is second-class bright stars. The connecting line between γ and α extends along the direction from γ to α, which is about four times the distance between two stars, that is, the south celestial pole, that is, the south. The stars α and β on the east side of the Southern Cross are the first-class bright stars in the southern sky. The vertical line connecting α and β through α also points due south.
