Our planet is pretty amazing and unique. It’s the only planet in our solar system that has life, as far as we know, and it’s also the prettiest. (We may be biased here, but you should always be biased towards your mother’s beauty.) There’s always something new to learn and discover about this living rock hurling through space that we all share, so here are 25 Shocking Facts You Never Knew About Earth!
Most people know that Earth is the only planet in our Solar System with an atmosphere that readily supports life (oxygen & water). What most people don't realize is that Earth is one of only four terrestrial planets (meaning it's rocky at the surface). Venus, Mars and Mercury are the other three.
Every 100 years the Earth's orbit spins approximately 2 milliseconds slower. We're slowing down.
Surprisingly, we haven't explored much of Earth. About 71% of the Earth's surface is covered by water, and we've barely explored the oceans. In fact, less than 10% (some say at little as 5%) of the oceans have been explored. Over 200,000 marine species have been identified in the 10% that's been explored, so just imagine what's left down there that we have no idea about.

Despite most of the Earth's surface being covered in water, 68% of the fresh water on Earth is permanently frozen as ice caps and glaciers.
The Earth isn't perfectly round. It's slightly football shaped due to it's constant spinning. So despite the perfect sphere we so often see depicted, it's actually a little squished.
