Moon problem

1, the moon itself can't shine, but can only reflect sunlight. When the moon is at different angles to the sun and the earth, you will see that the moon presents different faces, which is why the moon changes roundly;

2. The solar eclipse starts in the west and ends in the east; The eclipse begins in the east and ends in the west;

The representative constellations of the four seasons are: Leo in spring, Scorpio in summer, Pegasus in autumn and Orion in winter. Constellations near the north celestial pole, such as Ursa minor and Ursa major, can be seen in the northern latitude of the northern hemisphere all year round.

No, I can't see the moon all day on New Year's Eve. It should be around the seventh day of the seventh lunar month. It is not good to observe the crater on the fifteenth day of the lunar calendar. Because the sun is at right angles to the line of sight on the seventh day, the observation effect is better;

5. Because the moon is pulled by the gravity of the earth for a long time, its rotation period is strictly equal to period of revolution. So the moon always faces the earth.
