What is the difference between a planet and a star?

A planet is a big rock that goes around a star. A star is a big ball of hot gas that makes light and heat. Planets don't make their own light, but stars do!

A planet is a big ball of rock or gas that goes around a star, like the Earth going around the Sun. A star is a big ball of hot gas that gives off light and heat, like the Sun. So, planets go around stars, and stars give off light and heat.

A planet is a big ball of rock or gas that orbits around a star, like our Sun. Planets don't make their own light, but instead reflect light from their star. A star, on the other hand, is a big ball of hot gas that produces its own light and heat through a process called nuclear fusion. Stars are much larger and hotter than planets, and they are the center of their own solar systems.
