Ours is the fifth-largest planet in our solar system. Only Mars, Venus, and Mercury are smaller.
The Earth travels around the Sun at 67,000 miles an hour.
The Earth does not sit perfectly upright, but is tilted at an angle of around 23 degrees. It is this tilt that points different parts of the Earth slightly closer to the Sun as we travel around it, giving us our seasons.
The Earth’s diameter, going straight through the middle, is around 7900 miles.
The Earth’s longest mountain range can be located underwater. The so-called Mid-Atlantic Ridge is an enormous chain of submarine mountains that runs down the middle of almost the entire Atlantic Ocean.
Because a desert is officially defined as an area that receives little to no precipitation, the world’s largest desert is actually Antarctica, not the Sahara.
There are 300 cubic million miles of water in the Earth’s oceans.
