Hi, after glowing off, the small size meteorites passes thru Stratosphere with temperatures of minus 60 °C in winter and -10°C in summer. During their minute-flight thru the atmophere they warm up to normal temperature.
Only large objects which fly til the ground with hight supersonic speed (like Sikhote Alin) contact the ground with temperatures above 500°C. What I will say, the temperature depends on the landing speed. If it is the normal velocity of fall of earth gravity the meteorite is cold, if it is supersonic speed, it could be very hot. m42protosun -----Original-Nachricht----- Subject: [meteorite-list] Temperature of meteorites Date: Tue, 23 Nov 2010 00:34:24 +0100 From: [email protected] To: "Chris Peterson" <[email protected]> Cc: [email protected] Hi all: I am in the middle of a workshop on asteroids and meteorites. At the end of the first day, the teachers get to write down questions that they would like answered. During the session, I had said that when they land, meteorites are cold, not burning hot. The question that was asked was "how cold?" What is the best estimate we have for the ambient temperature of meteorites after they have passed through the atmosphere? Thanks.
