Here's a breakdown:
* Solar System: Our sun and the planets, moons, asteroids, and comets that orbit it.
* Galaxy: A massive collection of stars, gas, dust, and dark matter held together by gravity. Our solar system is located within the Milky Way galaxy.
* Universe: The entirety of space and time, including all galaxies, stars, planets, and everything else.
There are billions of galaxies in the observable universe, each with its own collection of stars and planets. Our solar system is just one speck in this vast and awe-inspiring universe.
