Hello, Earthling!

I’m Universe, and I’m here to tell you about some of my best parts, like your amazing planet, Earth. It’s my pride and joy.

You live on Earth, but do you know how incredible it really is?

Let’s start with its solar system.

There are eight planets there!

Earth is the third planet from the sun. And each of the planets—including yours— orbits around the sun on its own path.

It’s still pretty hot on the inside, even today.

And, as you know, the outside is crusty.

The crust you are sitting on right now is rock formed from cooled magma—that hot, bubbling, gassy mess I told you about.
