The forces of gravity and inertia wold keep planets in orbit,and without one of these a planet will crash into another planet and crumbles.The sun has a huge gravitational pull.
What Two Forces Keep The Planets In Orbit Around The Sun?
Gravity and inertia
Gravity works with the sun to hold it in place, and inertia keeps the mass of the planet attractive with the gravitational pull. I just learned this so DON'T BLAME ME IF I AM WRONG!!!!!!
It's the force of gravity
The planets stay in their orbital track because of the force of gravity between the sun and the planets. The planets stay moving because of the forward momentum. In the vacuum of space there is no drag to slow them down.
The two forces that hold a planet in Orbit are the gravitational force and the Centrifugal force. Gravitation is the property of the space time continuum. When massive objects like Earth or even more massive ones form in space they cause space and time to curve and gravitation is the result of that force. Since Sun is the most massive object in the Solar system it tends to keep all other planets in orbits around it. The other force is the Centrifugal force which is responsible for the circular motion of the planets and results from the interaction of their respective gravitational fields.
The force that keeps planet around the Sun is Gravity. In Newtonian Physics we were led to believe that Gravity is actually a Force which causes Celestial Bodies to suck or exert a force on objects in order to keep them around themselves in stable orbits. However, with the advent of Einstein's Special and General theory of relativity the concept when applied to gravity, we figured that gravity is actually a property of the Space-Time continuum's geometry and as massive objects tend to curve the spatiotemporal fabric we experience it as a weak force which causes celestial orbits to exhibit this property. A more massive celestial entity tends to attract the less massive ones around itself and the less massive ones will tend to exert an equal and opposite centrifugal force which causes them to stay in orbits around the Sun.
Gravity and inertia keep the planets in orbit.
Gravity and inertia I guess. But I think it IS TRUE!!!!!
Gravity.. Duh
Centrifugal(force from outside)and centripetal(force acting 4m the center)
