1] There Are Not 24 Hours In a Day.
People often claim there aren't enough hours in the day and they're right – not even 24. That's right, the actual time it takes the planet to rotate on its axis is 23 hours 56 minutes and 4 seconds. This is what's called a sidereal day. The solar day, the time it takes for the sun to return to the same spot on the meridian, varies as much as 16 minutes throughout the year, due to the position in its orbit.
2] The Name “Earth” Comes From Anglo-Saxons.Also,Earth is the only planet not named after a Greek/Roman God/Goddess
Every other planet in our solar system is named after a Greek or Roman God, except our planet. The word Earth comes from the Anglo-Saxon word Erda, which means “ground” or “soil” and is thought to be 1,000 years old. Ironically, the planet is covered by 71% water -- the only planet we know of in the entire universe to have this precious fluid in liquid form.
3] Earth Had a Twin Planet Called Theia.
Scientists now believe that we were once not alone in our orbit around the Sun – we had a “twin” planet we call Theia, which was the size of Mars and was 60 degrees either in front or behind our Big Blue Ball. One afternoon about 4.533 billion years ago, Theia crashed into the Earth; most of the planet was absorbed, but a large chunk blew off and combined with materials from our planet to create the Moon.
4] The Oceans are over 90% Unexplored
So we've (allegedly) been to the Moon and to Mars, but guess what? We have barely begun to visit the depth of our vast oceans. In fact, less than 10% of the deep blue seas have been explored. The ocean contains 97% of our water and 99% of the living area. While we have identified 212,906 marine species, there are possibly 25 million more that we DON'T know about. Suddenly, the Loch Ness Monster doesn't seem so far-fetched.
6] The Highest Point on Earth Is Not Mount Everest.
True, it's one of the most famous mountains in the world, and at 29,035 ft. above sea level it's pretty darn tall. However, considering we now know that the Earth is not round , anyone or anything along the equator is slightly closer to the stars. This means that although Mount Chimborazo in Ecuador is just 20,564 ft. above sea level, because it is on this “bump” it is technically further away from the Earth's center (i.e. “higher”) than Everest by 1.5 miles!
