So far, Earth is the only planet to sustain life as we know it. It is also the only planet that appears to have liquid water on its surface and this is not the only remarkable thing to note about the Earth’s surface. It is split in to tectonic plates that move on top of a layer of rocky mantle, that in turn covers red hot molten liquid at the planets core.
Where is it in our Solar System?
The Earth is the third planet from the Sun and sits between Venus and Mars. It is a staggering 93 million miles from the Sun, that is the equivalent of walking around the equator just under 3735 times!
The distance in space is sometimes measured using AU, the astronomical unit. 1 AU is equal to the distance between the Sun and the Earth.
A year on Earth is defined by how long it takes for the earth to orbit the Sun, this is equal to 365 1/4 days. We however take a year to be 365 days and save up the 1/4s until the fourth orbit, in that year we get an extra day, February 29th, making it a leap year!
The Earth is approximately 4.6 billion years old.
Oceans cover around 70% of the surface of the Earth, in fact the deepest place on Earth can be found under the ocean, some 35,813 feet below sea level, it is called the Mariana Trench.
It takes around 8 minutes 19 seconds for the light from the Sun to reach the Earth, that is 8 minutes and 19 seconds to travel 93 million miles!
Even though it looks round, the Earth actually has a bulge around the equator.
