Here's a breakdown:

* Planets don't produce their own light. They are just giant balls of rock or gas.

* Sunlight illuminates them. Just like the moon, planets reflect the light from the sun.

* We see the reflected light. The reflected sunlight from planets is what makes them appear as bright points in the night sky.

Why are they visible at night?

* Earth's rotation: The Earth rotates on its axis, causing the apparent position of stars and planets in the sky to change throughout the night.

* Orbital positions: The Earth and other planets are constantly moving in their orbits around the sun. Sometimes, our position in relation to a planet is such that we can see it in the night sky.

Important Note: While planets reflect sunlight, they are not as bright as stars. This is because they are much farther away than stars, and they are smaller than stars.
