Gravity and Inertia keeps the earth in orbit
The sun's gravitational pull keeps the earth in orbit around it.
The force that keeps the moon in orbit around the Earth is gravity. Specifically, the gravitational pull between the Earth and the moon is what keeps the moon in its elliptical orbit.
gravity
earth's gravity
gravity and inertia combine to keep earth in orbit because the suns gravity keeps the earth in orbit and the inertia keeps the earth from going in a straight line.
The Sun
The earth is six times more massive than the moon. That keeps the moon in orbit around it, just as the mass of the sun keeps the earth in orbit around it.
its called gravity
The gravitational force.
The balance between the inertia of the Moon and the gravitational pull keeps the moon in orbit with Earth.
The moon keeps moving in its orbit around the Earth due to its inertia and the gravitational pull of the Earth. There is a balance between the moon's velocity and the gravitational force that keeps it in a stable orbit.
