What keeps the earth in the solar system?

Answer 1

It is the gravitational force between Sun and Earth that acts as centripetal force and keeps earth in orbit.

As with all other bodies in the solar system of which Earth is a part, the centripetal force that maintains Earth's orbit around the sun is the result of the gravitational attraction between the Sun and Earth.

The gravitational pull of the Sun keeps the Earth in its elliptical orbit and balances the Earth's tendency to continue moving in a straight line. These two factors together keep the Earth in the solar system. The gravitational force of the Sun keeps the Earth in orbit around the Sun, preventing it from flying off into space.
