Subject: Not like Pluto collision with Neptune...
|
Ok, just to get this straight, I know that Neptune and Pluto not colliding unless an event of astronomical proportions (ya, that was a pun) caused them to. It is because Pluto, even though their paths cross, is 15 degrees "above" (This is relative to my mind, ok, can't really explain it well) Neptune. But what if Neptune and Pluto, after thousands/millions of years from now cross paths at their meeting point, could their gravitation pull be strong enough even at that distance? And furthermore, could they eventually become so close that they collide? Please respond

Please respond > The motions of Pluto and Neptune are such that there is a gravitational resonance between them, such that not only won't they come close to one another (no more than 1 AU or more) but their paths actually keep them away from one another.

Please respond What makes most orbits in the solar system stable is that they are in some sort of resonance with nearby bodies of significant mass. If the above scenario could happen, given their respective orbital periods, then Pluto wouldn't be where it is today. - Greg Crinklaw Astronomical Software Developer Cloudcroft, New Mexico, USA (33N, 106W, 2700m) SkyTools: http://www.skyhound.com/cs.html Observing: http://www.skyhound.com/sh/skyhound.html Comets: http://www.skyhound.com/sh/comets.html To reply take out your eye

I am the dor and here is what I suggest. Don't cover his head with a sheet. I would suggest to cover his head with a tin foil hat. That'll be $500 for the advice. Most insurance plans are welcome. So is cash. -- Martin R. Howell "The Astro Post" www.theastropost.com -- Posted via a free Usenet account from http://www.teranews.com
