As we have found from studies of our European Fireball Network, the=20 cometary material that hits our atmosphere is very soft and has an = extremely=20 low density (between 0.2 ang 0.6 gram/ccm). We have photographed really heavy chunks of cometary material enering = our atmosphere (producing spectacular bolides), but they ALL burnt up and = NEVER=20 did any piece reach the ground - even if they had initial masses of = several tons! A comet fragment of 1 km diameter would have good chances to survice its fiery flight, but not in my backyard, PLEASE... A meteorite fall on the peak day of a meteor shower? Why not - but in my = eyes this is pure coincidence, but no correlation. My two cents Dieter ----- Original Message -----=20 From: Rick Nowak=20 To: meteorite-list_at_meteoritecentral.com=20 Sent: Friday, February 08, 2002 5:32 AM Subject: [meteorite-list] Leonid Meteorite I was wondering is their a documented for sure 100% meteorite that came from the comet Temple Tuttle?? We know that the Leonids come from this comet. Just maybe their is meteorite out their????? Rick __________________________________________________ Do You Yahoo!?
