User: Why does the Earth revolve around the Sun?
Assistant: The Earth revolves around the Sun due to gravity. The more mass an object has, the greater its gravitational pull on other objects. The most massive object in the solar system is the sun, which is actually one of the larger yellow dwarf stars in the universe. With a mass of 1.98892 x 10 to the 30th power kilograms, the sun has approximately 333,000 times more mass than Earth. Because the gravitational pull of the sun is so much more than the Earth's gravitational pull, the Earth is forced into an orbit around the sun.
