Scientists have calculated the age of the Earth through dating both the oldest rocks on the planet and meteorites that have been discovered on Earth's surface (Earth and meteorites formed at the same time when the solar system was forming). They found that Earth is about 4.54 billion years old, according to the National Center for Science Education. So if you ever feel old, think about this fact.
2. Earth is the only known planet to contain life.

Scientists have been scouting our solar system, as well as other solar systems to see if any other planets host life, but so far it seems that Earth is the only planet to support life.
3. It's spinning super fast.

The planet rotates at around 1,000 miles an hour, but although the whopping speed, we don't feel the Earth itself spinning because we are held close to its surface by gravity.
4. Earth isn't perfectly round.
It may look round, but it's actually not so much. The Earth bulges around the equator by an extra 0.3 percent due to how it rotates about its axis.
5. You can fit more than a million Earths in the Sun.

If the Sun was hollow, due to the whopping size of our star, Earth can be fitted about 1,300,000 times in it.
