In our Universe, angular momentum is a conserved quantity. What that means is that, once a planet is orbiting a star at one speed and radius, neither of the latter two can possibly change unless some outisde force (more precisely, a torque) acts on that planet. Long ago, all planets going around our Sun achieved specific speeds and radii of orbit -- and, in our Universe, they'll maintain both of those for billions of years.

Planets do not collide with each other because they follow predictable orbits around the sun due to the gravitational forces acting on them. The distances and speeds at which planets orbit are carefully balanced to prevent collisions. Additionally, space is vast, so the likelihood of two planets colliding is extremely low.

They travel on an imaginary axis around the Sun. The Sun's gravitational pull keeps the planets from drifting away.

Why planets do not collide with each other although there is strong gravitational force between them?

Planets do not collide with each other because they orbit around the Sun in stable paths called orbits. These orbits are a balance between the speed of the planet and the gravitational pull of the Sun. The gravitational force between planets is not strong enough to overcome the momentum of their orbits and cause them to collide.


Why the planets not colliding each other?

The planets in the solar system are in well-spaced out, stable, roughly circular orbits - they don't come close enough to collide with each other. Asteroids and comets, however, are on more elliptical, unstable orbits that often cross the orbits of the planets, and sometimes planets collide with asteroids and comets.


Why don't planets collide with each other because of gravity?

In the past some planets or protoplanets did collide with each other. Indeed we believe that the Earth/Moon system was created by just such a collision. We can also see comets crashing into planets to this day. However, the solar system is now much more stable and the major planets now orbit the Sun (because of the Sun's gravity), each following their own orbital path. Each orbital path is separated by millions of miles and while the planets' gravities do tug one on another, this is not enough to destabilize the orbits.


Do Each of the eight planets share an orbit?

No, each of the eight planets in our solar system orbits the sun on its own path defined by its distance and speed. This unique orbit for each planet is what allows them to maintain their positions and not collide with each other.


Why planets do not collide while revolving around the sun?

Because if they were ever going to collide they would have done it at some time in the last 3.5 billion years. Each planet has its own stable orbit which takes it round the Sun regularly at a fixed range of distances that does not overlap with other planets. The planets are understood to follow Kepler's laws in elliptical orbits, under the force of the Sun's gravity.

Why cant planets share rings?

because if the planets were close enough to each other to be able to have a gravitational pull strong enough to share rings, the planets would ultimately collide

Why don't planets bump into each other?

because the gravatational pull from the sun and other planets keep the planets going in a circler motion and not bumping into each other.Answerbecause the gravatational pull from the sun and other planets keep the planets going in a circler motion and not bumping into each other. the planets each have defined Elliptical, not circular, orbits that remain constant because of gravitational pull of the sun and from each other. Pluto does have such an elliptical orbit that for a time it was closer than Neptune, but they will never collide with their current paths.

Why don't planets collide?

Planets do not collide because of gravitational forces that keep them in stable orbits around the sun. These gravitational forces cause planets to travel in predictable paths without intersecting each other's orbits. Additionally, the vast distances between planets in our solar system help prevent collisions.

Do planets collide when the distance of the planets from the sun change?

The distance of the planets from the sun does not change because of the gravity surrounding each planet is pulling them into continuous orbit.


Why don't planets have the same orbit?

If they did then they would collide. They could merge into a larger planet or get blasted into space. In the latter case, the smaller parts would continue in individual orbits until they were attracted, by gravity, into other planets or coalesce into a new planet.
