Astronomy Activity: Solar System, Galaxy, Universe: What's the Difference?

Imagine you're playing with toy cars on a big floor, that’s like our solar system.

Your toy car is Earth, and it zooms around the sun, which is like your favorite red block in the middle of the floor. All the other toys, like Mars or Jupiter, are also going around the sun. That whole group is called the solar system.

Now, imagine you have a bunch of floors stacked on top of each other. Each floor has its own toy cars and blocks. That’s like a galaxy. Our galaxy is called the Milky Way, and it has billions of stars, just like your toy cars, but way more!

And then, if you had a whole building full of these floors, that would be the universe. The universe has millions of galaxies, each with their own solar systems. It's like a giant, never-ending toy box.

So:

• Your playroom is the solar system.
• One floor in the building is a galaxy.
• The whole building, and all the floors inside it, is the universe. Imagine you're playing with toy cars on a big floor, that’s like our solar system.
