Earth: Facts about the Blue Planet

Earth is our home planet, the only place in the universe where we know for sure that life exists. Earth formed more than 4.6 billion years ago from a swirling cloud of gas and dust that created the entire solar system, including our star, the sun. Scientists theorize that this gas and dust has collapsed into a disk, with different parts of the disk coalescing to form individual planets in the solar system.

Where is the earth located?

Our planet is located in a small corner of Galaxy galaxy, 25,000 light-years from the galactic center, according to NASA. The solar system rests on a sub-branch known as the Orion Spur, which splits off from the Sagittarius arm, one of the galaxy’s two main spiral arms. Earth: Facts about the Blue Planet
