[meteorite-list] meteor velocity

[Jose Campos]

Hi George Z. and Marco L. (and List),   Many, many thanks for all your interesting info on the relative meteor velocities and on their possible asteroidal or cometary origins. I suppose that the Earth's gravitational attraction onto these meteoroids would not account too much, on their slow, or very fast relative velocities?   On a slightly different matter: What would you think that, considering its ~60 Ton mass, the great HOBA meteorite's entry velocity might have attained on atmosphere entry? And why was it that most of it, did no desintegrate to smaller fragments? Was it because of a very low velocity? (which implies an asteroidal origin). And what could possibly might have been its trajectory angle in relation to the ground? (a very low angle, in order not to become half-buried and/or not to break-up on impact?). Even at a lower minimum velocity of some 11 km/s, why is is that it did not made a small hole/crater on the ground? (unless if its vestiges have been eroded with time, bearing in mind it's estimated 80.000 yrs since it fell to the ground). Any comments on this?   Jos�
