Re: Odds

More than that. I'd argue the period of time where NEO were a danger has passed. The local neighbourhood has cleared.

As an example of the risk, with galaxy collisions the predicted number of stellar collisions is around a dozen or two. That's very low for the amount of stars between two galaxies.

So while were not talking about planets hitting planets (unless we reclassify Pluto ;) ). We are talking about the odds while the system is currently in a rather stable state.

What are the simulations on collisions within a solar system with an age of ours? Unlike Galaxy collisions, we don't seem to have any local neighbours on a collision course. Most of our surrounding matter is orbiting in unison (around the Sun, or with our solar system around the Galaxy's core).
