Earth, our beautiful home planet, is the only astronomical object to accommodate life as we know it. Scientists believe Earth was formed approximately 4.5 billion years ago. It is the fifth-largest planet in our solar system. Its equatorial diameter is about the third-closest planet to the sun. The distance from Earth to the sun is roughly 149,600,000 kilometers.
