Orbital momentum (or inertia) keeps the planets moving per Newton's First Law; gravitational pull from the Sun causes the orbit to assume an elliptically-shaped path. If effect, they constantly fall (accelerate) towards the Sun but constantly miss it.
An explanation appealing to general relativity might assert that gravitation in an effect in which mass curves spacetime, and that planets only travel in straight lines (geodesics) through curved space.
The force that keeps planets in orbit is gravity. Gravity is the attractive force that exists between two masses, such as a planet and a star, that causes them to be drawn towards each other. In the case of planets orbiting a star, gravity keeps the planets in their elliptical paths around the star.
Gravity.
The gravitational force exerted by the Sun keeps all the planets in their orbits. This force balances the planets' tendency to move in a straight line and keeps them moving in elliptical orbits around the Sun.
Gravity
It was Isaac Newton who figured out that the force of gravity keeps planets in orbit around the sun.
it keeps it in orbet
The force that keeps all of our planets in rotation is gravity.
The force of gravity.
The gravity of there star keeps them on path and a planets moon is sun around by its planets gravitational force
Apparently so, because that's how it is.
