Stars are big balls of fire in space. They make their own light and heat. The Sun is a star, but other stars look small because they are very far away.

Answer

Constellations are groups of stars that form patterns in the sky. For example, Ursa Major looks like a big bear or a spoon. People use them to find directions.

Answer

A planet is a large space object that moves around the Sun in a fixed path called an orbit. Planets do not make their own light — they reflect sunlight.
