क्या कारण है कि उल्कापिंड इतने गर्म होते हैं कि आप उन्हें छू नहीं सकते?

उल्कापिंड - अंतरिक्ष से चट्टानें जो पृथ्वी पर उतरती हैं - पृथ्वी के सामान्य तापमान की तुलना में ठंडी होती हैं. इसका कारण यह है कि ये अभी गहरे अंतरिक्ष से आए हैं, जो ठंडा है. It is true that when a meteorite falls through the atmosphere, the air shock heats the outer surface until it is vaporized. But there is not enough time for this heat to reach inside the meteorite. In his book “Meteorites and their Parent Planets,” Harry Y. McSween states: “Although in some cases fusion crusts may still be warm, the interiors of these objects certainly are not. Meteorites have been stored in the deep freeze of space for eons, an atmospheric heating does not significantly affect their interiors because heat conduction in stones or even iron takes much longer than the minute or so required for atmospheric transit. The Colby (Wisoncsin) and Dharmasala (भारत) meteorites are reported to have been quickly coated with frost, even though both fell on hot days in midsummer.”
