[meteorite-list] Fw: Astronomy Picture of the Day

Jose and list:
   
  If the meteorite has spent eons at space temperature and only spends a few seconds heating the surface as it descends through our atmosphere, why shouldn't it still be cold from the low internal temperature of the material?

  Hi Stefan,

Thanks for the link.
However, the captation that goes with it says:
Quote " If you are lucky enough to find a meteorite just after impact, do 
not pick it up -- parts of it are likely to be either very hot or very 
cold". End of quote.

That is unfortunately, quite a common popular belief, that from an 
educational point of view, must be fought off.

During the meteorite's free fall to the ground, it has enough time to cool 
down to the point that, on being pick up from the ground, a person do not 
experiences any heat or, for that matter any cold from it - and its 
temperature will not be much different from any other stone near by.
