Fw: [meteorite-list] Origins

[Jose Campos]

Hi List, The probability of a meteorite originated from Mercury, being able to reach Earth (or Venus or Mars, for that matter), must be exceedingly small, as it would be strongly attracted towards the Sun, unless its initial orbit would be disturbed in such a way as to be "kicked out" by a close encounter in the Sun's vicinity,  with a passing asteroid or a comet?   José   ----- Original Message ----- From: MARK BOSTICK To: Martin Altmann ; [EMAIL PROTECTED] ; Meteorite List Sent: Saturday, June 12, 2004 2:20 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. Here a picture of the orbit http://www.heise.de/tp/deutsch/special/raum/14785/1.html   Martin ----- Original Message ----- From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] ; [EMAIL PROTECTED] Sent: Saturday, June 12, 2004 10:28 AM Subject: Re: [meteorite-list] Origins [EMAIL PROTECTED] writes: What about Mercury, Saturn, Jupiter...Etc? 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.
