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.

Why don't planets collide?

All the planets are in stable orbits around the sun and never come close enough to be significantly affected by each other's gravity.


Why are the dwarf planets round?

because of the gravity of the other planets around them


Why does earth have gravity and other planets don't?

The other planets do have gravity.


Does earth have strong or weak gravity?

Because of Earth's size, and considering it as one of the smallest planets, it has a weak gravity compared to the OTHER planets. Most planets have greater gravity because of their size. Earth has a stronger gravity compared to mars, mercury, and venus.


Is it true that- gravity holds planets in orbit because planets are attracted to each other's gravitational force?

It's true that gravity holds planets in orbit. However, this is due to the gravitational influence of the sun, not the gravitational influence of other planets.


Why planets do not collide while revolving around the sun?

Planets do not collide while revolving around the sun because they have stable orbits and follow gravitational laws. The gravitational force between the planets and the sun keeps them in their respective orbits. The speed and direction of their orbits ensure that they maintain a safe distance from each other, preventing collisions.


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.


Why do earthquakes occur on other planets?

Because the planets still have gravity. Thing of an earthquake like a house settling. As gravity pushes down on the house, the house ever so slightly moves itself. The effect is amplified with planets; they are "settling" because of their own 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


Will all of the planets collide at one point?

(well in pics) but it really wont happen because earth is like a big magnet but the gravitational pull will not let the other planets collide with the earth or (even the sun) some say !!


Why do the planets don't fly away?

Because of Gravity or Because their gravitational pull towards the other planets or sun keeps it in one place.


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
