Why do stars shine?

1 It is a star, and it will shine like the sun.

The light it reflects from other stars.

In fact, the moon itself does not shine, and we see that its light is reflected by the sun. The stars don't look as bright as the moon, because the stars in the night sky are far from us, so they don't look as bright as the moon. In fact, stars outside the solar system are much bigger than the sun.

Little sister, it's good that you are good at observing life.
