Jo Mark,   In my little world I have no idea whether at all or from which reservoir the asteroid belt could be filled up nowadays, only the comet cores, which were captured by Jupiter on short periodic tracks, come into my mind.   We have to ask the celestial mechanics on that list. Also the ratio of the probability to catapult a body from the inner solar system out on a stable orbit, let's say with an aphelion in the main belt and a perihelioin somewhere around Mercury's orbit versus the same orbit but thrown from a collision in the main belt into the inner solar system would be interesting, or not so?   Martin ----- Original Message ----- From: MARK BOSTICK To: Martin Altmann ; [EMAIL PROTECTED] ; Meteorite List Sent: Saturday, June 12, 2004 3:20 PM Subject: Re: [meteorite-list] Origins Hello Martin and list,   Not saying Enstatites are from Mercury, it seems to me that they formed much further from the sun.....but doesn't everything get kind of pushed into the asteroid belt?  That was my understanding why there are still asteroids in the belts.....they get replaced.       Mark Bostick www.meteoritearticles.com       ----- Original Message ----- From: Martin Altmann Sent: Saturday, June 12, 2004 6:28 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: [meteorite-list] Origins   The Enstatite Chondrite Neuschwanstein had its aphelion in the asteroid main belt, thus it's not related to Mercury.

Is it just because we have to point of reference or maybe distance...Just Curious! There was widespread belief that the Enstatite Chondrites originated within Mercury's orbit, if they weren't actually Mercurian themselves, but I haven't read any particularly recent scientific assessment on that position....any updates out there?   The "giants" (Jupiter and Saturn) are considered to be essentially gaseous with prohibitive escape velocities as well, so I don't think there's much speculation about them being reasonable candidates for parent bodies.
