The Sun.
The gravitational force.
You mean 'keeps in the orbit of the sun? Gravitational force of attraction keeps the earth going around the sun.
The earth by its gravitational pull keeps the moon in its orbit. The earths gravitational pull and the Moon's inertia creates a force called the centripetal force which keeps the Moon in orbit.
The force of gravity, specifically the gravitational pull between the Earth and the Sun, keeps the Earth in orbit around the Sun. This gravitational force creates a balance between the Earth's motion and the pull of the Sun, causing the Earth to continuously orbit around the Sun in a stable path.
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.
The sun's gravitational pull keeps the earth in orbit around it.
The moon orbits the Earth due to the gravitational pull between the two objects. This gravitational force keeps the moon in its orbit around the Earth.
The moon is held in place by the gravitational pull of the Earth. This gravitational force keeps the moon in orbit around the Earth, preventing it from floating off into space. The balance between the motion of the moon and the gravitational force of the Earth keeps the moon in a stable orbit.
The Earth's gravitational force keeps it from moving away into outer space. (* Gravity is a mutual force of attraction between matter, so the Earth pulls on the Moon while the Moon pulls on the Earth.)
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 is the force that allows satellites to orbit the Earth. The gravitational pull between the Earth and the satellite causes the satellite to continuously fall towards the Earth while moving forward at a speed that keeps it in orbit.
The Earth orbits the Sun due to the gravitational pull between the two objects. This gravitational force keeps the Earth in its elliptical path around the Sun, maintaining its orbit.
