We have day and night because the earth keeps moving all the time. Just because the moon is closer to the earth than the sun, it looks much bigger than the sun.
The sun is bright enough to give out very strong light. The moon can’t give any light at all, but it looks quite bright, too. Why? In fact, the light from the moon comes from the sun. (2)But in fact the stars are much bigger and brighter than the moon.
