Re: [meteorite-list] Hot vs. Cold again...

Also important is to consider that the body in space may well have been a good fraction of a meter (or more) across. But a meteorite producing body didn't just ablate, it most likely fragments. And the small fragments very, very rapidly drop below the speed necessary to sustain ablation. So

This was looked into several times in the list history. I am recalling details from those discussions/my research. Any body arriving from space is at least -60°c and closer to -120°c to -180°c based on some black body studies of asteroids-- IIRC The temperature at the air-meteoroid boundary

Re: [meteorite-list] Meteorite Crashes Through Thailand House Roof

Hi Bob, I agree that some people are burned by the cold. But after reading many first hand reports I think that the “cold enough to burn” meteorites are those that are found ON the ground. The “too hot to touch” meteorites are the ones that have punched through something. I can’t prove it,

Re: [meteorite-list] Meteorite Crashes Through Thailand House Roof

There's really no way for such a stone to be heated significantly by the energy dissipated when crashing through a roof. In all likelihood, the reason that observed falls are reported as hot is because people expect hot, and confuse hot with cold. I don't think the incidence of reports of

Peter, I'm going to go with the theory she was mistaken. I'm sure the crash kind of messed her mind up a tad at the time of impact. Regards! Tom On 06/28/2016 04:29 PM, Peter Scherff wrote: Hi Tom, Yes, I think so. There are too many reports of meteorites being hot to the touch. Those

[meteorite-list] Meteorite temperature (again)

If the meteorite had a temperature significantly different from ambient, I'd go with extremely cold (e.g. -30 F). To the unsuspecting, bitter cold could be misinterpreted as very hot. If you don't believe me, try putting a clothes iron in the freezer for a couple hours and then surprise someone

Hi Tom, Yes, I think so. There are too many reports of meteorites being hot to the touch. Those reports are almost always about meteorites that have punched through something (building, vehicle or ground). I trust this mass of anecdotal evidence. But we won't know for sure until some starts
