Earth

Earth is the third planet from the Sun and is the only planet in our solar system not to be named after a Greek or Roman deity.

The Earth formed approximately 4.54 billion years ago, is the only known planet to support life.

Do you know?  The Earth’s rotation is gradually slowing.

This deceleration is happening almost imperceptibly, at approximately 17 milliseconds per hundred years, although the rate at which it occurs is not perfectly uniform. 

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.
