Would gravitational forces prevent them?

Not impossible, but highly unlikely, as first you'd need to knock one planet out of its orbit with an asteroid, and it would have to be a really BIG asteroid to do that. Chances of that happening - very low.
Gravity will help cause a collision by bringing two planets together.

Would gravitational forces prevent them? In our solar system, planet to planet collisions are impossible. Thinking that an asteroid could "knock one planet out of its orbit" is just silly. You been drinking today Monkey? |

You been drinking today Monkey? No, they are not impossible. That's the 'silly' statement. If a large enough force upsets the equilibrium, it's completely possible. An asteroid doing it is not at all silly. As I said, if it was big enough, it could. I'm sure you've played pool so have seen what collisions can do. Do you have an engineering degree that involved studying gravity? If not, stop saying people have been drinking when they bring their knowledge to a discussion. |

Asteroids hitting planets is nothing at all like billiards. Nothing. I'm not trying to insult you. You normally come off as a pretty bright guy. But come on. |

So you must have studied the mathematics of impacts? And billiards is a decent representation of space bodies. It shows how bodies behave in collisions. What do you think is the difference in the general behaviour between colliding bodies in space vs on a pool or billiards table (other than one is 2-D and the other 3-D)? |

What do you think I was referring to when I said separately in two posts: "and it would have to be a really BIG asteroid" "As I said, if it was big enough" So, no. Won't change the general way they behave. Objects on table are of similar mass; objects in space are of similar mass. Their behaviour will be approximately the same. |

Two planet-sized masses hitting each other are not going to behave at all like billiard balls. |

Good, you have also not paid attention to me saying 'approximately' and 'general principle' when referring to collisions. Now, please explain how a planet-sized mass hitting the Earth will not affect Earth's orbit. It clearly will, but you seem to think that's 'silly', so I'd love to hear it. |

This has gone beyond absurd. What the fuck are we even arguing about? Look...There is no planet-sized mass going to hit the earth anytime soon. Look...If two planet-sized masses hit each other it ain't gonna be like billiards. Know what I think? I think you are babbling like an idiot because you know I would crush you in a game of chess. |

Look...There is no planet-sized mass going to hit the earth anytime soon. Look...If two planet-sized masses hit each other it ain't gonna be like billiards. 1. You know that? How? And so what? 'When' has never been part of this discussion. Stop trying to deflect, because you KNOW their orbits would be affected but refuse to admit the blindingly obvious. 2. In many circumstances it could be. You are assuming they collide head on. What if one creeps up behind the other and they collide at a relative speed of 10 miles per hour? That would be almost exactly like billiards, as would many other scenarios like it. The problem you have is that you are making sweeping generalised statements without thinking about the many potential angles of collision, the relative size of the bodies and the material they are made from. But that's what you get from thinking solely in mathematical terms. Pffft. |

"What if one creeps up behind the other and they collide at a relative speed of 10 miles per hour?" Are you even trying to be serious? |

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.
