About Our Planet Earth as a Planet
Planet Earth stands as the third rock from the Sun and the only known world in our solar system that supports life.
This blue marble spins through space at incredible speeds, traveling around the Sun at 67,000 miles per hour while rotating on its axis once every 24 hours.
What makes Earth special isn’t just its perfect distance from the Sun, but also its protective atmosphere and abundant liquid water.
The planet formed about 4.5 billion years ago and has been constantly changing ever since.
Earth’s unique combination of conditions creates the perfect environment for millions of species to thrive.
