I think that books from Jean Meeus could serve you. They contain formulas to calculate orbits, planetary positions, eclipses, conjunctions and maybe calculations for meteorites as well.
One thing to think about, though: the best you can say is where the meteorite entered the atmosphere, nothing more. Perturbances of the orbit are many with such a small body, and I would think that you cannot determine exact positions for more than a day or two back into the past. Even asteroids can't be calculated precisely with a formula for more than two or three orbits. After that, the miscalculations will be more than just a few arcseconds... _____ Best regards, Bernhard "Rendelius" Rems CEO RPGDot Network This outgoing mail has been virus-checked. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Pierre-Marie PELE Sent: Thursday, September 23, 2004 3:19 PM To: [EMAIL PROTECTED] Subject: [meteorite-list] Calculating a meteorite orbit Hello, I'm searching for an Excel program or a document explaining how to determine the orbit of a meteorite fallen on earth according to the fact that we know the impact point, trajectory, altitude and speed, pictures of the bolide. This technique of orbit calculation was used on Pribram, Lost City or Innisfree for example. I need your help ;-) Regards, Pierre-Marie Pele www.meteor-center.com ------------------------------------------ Faites un voeu et puis Voila ! www.voila.fr ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list
