Earth Day might not be until April, but that doesn’t mean we can’t still talk about it. There are a LOT of things going on these days, so why not stop and learn some science? We’ve rounded up 10 facts about Earth that will blow your mind.

If you’ve ever wondered why the Earth got its name or how dense it is, we’ve got your answers. Plus, with all these fun facts you will win the random fact category at any dinner party. You know you want to impress your friends, so read up!

1Golden planet.

If you collected the gold in the Earth’s core, you could cover the entire surface of the planet in 1.5 feet of the mineral. It would be golden!

2Every planet but Earth is named for a mythological god or goddess.

Seven out of the eight planets are actually named after Roman gods or goddesses. Earth however comes from the old English word, “ertha” which means ground or land.

3It’s all about the water.

About 70 percent of the planet’s surface is covered by water. The other 30-ish percent is made up of islands and continents.

4No other planet is as dense.

Out of the whole solar system, Earth is the most dense with the average density 5.52 grams per cubic centimeter, according to The Planets.

5A year is actually longer than you think.

Despite what we all celebrate, a 365 day calendar per year, every year on Earth has actually 1/4 of a day more than the 365 days. This is how we get the leap year every four years. Crazy, right?

6Mountains exist under the sea.

The oceans on Earth don’t just house sharks and coral reefs, they have mountains as well. In fact, the longest mountain range on the planet stretches 80,000 km and it’s called the mid-ocean ridge system. It’s way longer than the Andes Mountains!

7Don’t go to the core.

Everyone knows that the sun is hot, but you might not know the Earth is, too. At its core, it is about the same temperature as the sun. As in, it’s really, really hot.

8The rainforest is the place to live.

We all know that the rainforest is huge, but the Amazon also houses one third of the planet’s species.

9The North Pole isn’t just for Santa.

There is actually no solid land under the North Pole. It is just sea ice. But if you did visit the North Pole, you would weigh more than at the equator, because of the gravity.

10Lightning strikes more than twice…a day.

While everyone says that lightning doesn’t strike twice in the same spot, it does strike more than once a day on Earth. In fact, it strikes about 8.6 million times a day, so watch out.

Of course, there’s plenty more where these came from. After all, our planet is filled with some absolutely fascinating facts!
