How are the planets held in orbit?
Most people don't think this but planets are actually held in orbit by gravity. With out gravity the planets will fall down.
According to Newton what force held the planets in orbit?
Newton's model, which is still current for most purposes (with slight modifications by Einstein) has planets held in their orbits by gravitational attraction between Sun and planet.
Is a nebula held together of the outward force of gravity?
No an nebula is held together by the balance of the inward force of gravity and outward pressure.
Are the planets held in their orbits by unbalanced forces?
No. The planets are held in orbit by forces balanced against each other: The force of gravity from the sun would pull the planet into the sun destroying it. The momentum of the planet making it travel in straight line would result in the planet travelling away from the solar system. There are also other forces involved such as the pull from other planets on each other. Combined, they balance each other resulting in a planets circular/elliptical path orbiting the sun. Otherwise, the planet would have fallen into the sun, collided with other planets or other objects, or just flown away from the solar system long ago and we would never have known about it.The force that holds objects in orbit is gravity. In the case of our solar system, the planets are held in orbit by the gravity generated by Sol, our sun (a sun is a star with a satellite system).The inertia of the planets combined with the Sun's gravity keeps the planets in orbit. So, there's only really one force, gravity. However, the effect of inertia is sometimes referred to as "centrifugal force", although its not a real force.Objects in our solar system are kept from falling into Sol, the sun, by their centripetal motion (inertia). They are kept from flying off into empty space by Sol's gravity, generated by spacial displacement.They are held in orbit by the gravity of a celestial body of a greater mass. For example, the planets in our solar system are held in orbit by the gravity of the sun.
How newton discover gravity?
Newton did not discover gravity. He realized that the same force, gravitational force, that acts on all things here on earth go thru space and act on the moon to keep it in orbit. The same for the planets revolving around the sun.
How are the planets held in their orbit?
The planets are held in orbit by the gravity of the Sun, and also because that is what happens when the force of inertia and gravity are combined.
How are the planets held in orbit?
Most people don't think this but planets are actually held in orbit by gravity. With out gravity the planets will fall down.
Are planets held in place by gravity?
Yes they are the sun has gravity that holds the planets in place.
Did gravity held the planets in orbit?
Yes, and it still does! Because the Universe is electrically neutral and the nuclear forces have too small a range of influence, gravity is the only significant force at the scales of planets and such.
Why do the moons stay in orbit around Jupiter?
Any moon is held in orbit by gravity, just as the planets are held in orbit around the sun by gravity.
According to Newton what force held the planets in orbit?
Newton's model, which is still current for most purposes (with slight modifications by Einstein) has planets held in their orbits by gravitational attraction between Sun and planet.
Is a nebula held together of the outward force of gravity?
No an nebula is held together by the balance of the inward force of gravity and outward pressure.
Forces is responsible for keeping the planets in orbit around the Sun?
The solar system's planets, planetesimals, asteroids, and comets are held in orbit by the force of gravity, the mutual attraction between these objects and the Sun.
What force holds the planets in orbit around the sun?
It's the force of gravity which acts on the planets and keeps them in their orbits. Gravity works both ways but the Sun is more massive by far so does not move very much at all. The planets are caused to accelerate towards the Sun by gravity. They move in their orbits with velocities, at any moment, at a tangent to their orbital paths. The result is that they move in a continuous curve around the Sun. If they move slightly closer they speed up, which causes them to move out again, so the orbits are stable. Potential energy and kinetic energy are being exchanged all the time for each planet but the total stays constant.
Are the planets held in their orbits by unbalanced forces?

Could you land on the outer planets?
No. The outer planets do not have solid surfaces. Those planets are made of gases held together by gravity.
Why don't planets attract each other?
because gravity and inertia are kinda of playing a game of tug a war but both sides are equal so they do not move
