This has the effect of lengthening our days, but it happens so slowly that it could be as much as 140 million years before the length of a day will have increased to 25 hours.

This varies according to the part of the planet; for example, the metallic core is denser than the crust. The average density of the Earth is approximately 5.52 grams per cubic centimetre.

It’s actually 23 hours, 56 minutes and 4 seconds. This is the amount of time it takes for the Earth to completely rotate around its axis; astronomers call this a sidereal day. Now wait a second, that means a day is 4 minutes shorter than we think it is. You’d think that time would add up, day by day, and within a few months, day would be night, and night would be day.

Earth is mostly iron, oxygen and silicon

If you could separate the Earth out into piles of material, you’d get 32.1 % iron, 30.1% oxygen, 15.1% silicon, and 13.9% magnesium. Of course, most of this iron is actually down at the core of the Earth. If you could actually get down and sample the core, it would be 88% iron. 47% of the Earth’s crust consists of oxygen.

The continent of Asia covers about 30% of all the land. Around 60% of the world's population is located there.

Earth has a core underground in its center. The temperatures there have been estimated to be at 9.800 Fahrenheit / 5.400 degrees Celsius – This is even hotter than the surface of the Sun.

On average, one kilogram of Earth’s seawater contains 35 grams of salt.

Our planet is traveling through space at roughly 107,826 kilometers / 67.000 miles per hour. Since we are so small, we do not feel this incredible speed.

If all the people on Earth would jump at the same time, we could produce a magnitude 4 to 8 earthquake.

The Sun is gigantic! More than 1.3 million Earth’s could fit inside the Sun.

The first images of Earth taken from space happened on the 24^th of October, 1946.

The Moon is distancing itself from Earth about one inch every year.

Earth, along with the Solar System, is situated in the Milky Way galaxy. Our Solar System orbits the center of the Milky Way at a distance of 28.000 light-years away.
