Two planet size masses are not going to "creep up behind the other." There is a force called gravity that would prevent such an approach speed. Stop disagreeing with Monkey. You'll break him and then where will we be

Two planet size masses are not going to "creep up behind the other." There is a force called gravity that would prevent such an approach speed. If that's the case, then the impact would be substantial, right? But with a substantial impact, you still maintain that neither would have their orbits affected? And you still believe "In our solar system, planet to planet collisions are impossible" even though it's pretty obvious that a large enough asteroid could knock a planet out of its orbit so that it could collide with another?

Would gravitational forces prevent them? Let's summarise, because poor WVB seems to be obfuscating, tangentialising and unwilling to answer direct questions. There are a number of circumstances under which planets could collide. 1. A very large mass passes near or through a solar system, disrupting planets from their orbits and setting them on a collision path. Note that the collision could occur millions/billions of years later. 2. A large mass hits a planet with a glancing blow. Some of the planet would be destroyed, but the bulk holds together and its orbit is affected, setting it on a collision path as in 1. 3. A strange body that we have not encountered yet comes our way, namely something similar in size to a planet but with a very strong magnetic field that is opposite to the magnetic field of the planet it is approaching. Gravity draws them together, the magnetic field pushes them apart, resulting in a very slow collision so that they nudge each other out of their orbits with minimal destruction. Far fetched? Maybe, but it's a very large universe. 4. A very small solar system has planets the size of billiard balls. Because it is so small, the planets travel quite slowly to maintain their orbits. A mass passes nearby affecting their orbits and they collide like billiard balls. Due to their slow speed, there is no destruction and they just bounce off each other.
