From theCambridge English Corpus The asteroids, meteoroids and apparently all comets originated in the explosion of planets (or moons). From theCambridge English Corpus The sputtering model considered here may require significant modification for the case of highly fluffy and porous meteoroids. From theCambridge English Corpus Second, the time meteoroids have been travelling in space exposed to cosmic rays is relatively short, typically millions of years. From theCambridge English Corpus This kinetic energy goes into heating themeteoroidand the surrounding atmosphere. From theCambridge English Corpus Classical work onmeteoroidablation suggests that these particles should be annihilated by atmospheric deceleration. From theCambridge English Corpus As the evaporation of molecules from the surface of themeteoroidincreases, a vapour cloud starts to form around themeteoroid. From theCambridge English Corpus Heating of themeteoroidby direct impact causes it to lose mass by fragmentation and, as the temperature rises, evaporation and melting of its surface. From theCambridge English Corpus Two important lines of evidence that meteoroids originated in an explosion are these. From theCambridge English Corpus The meteoroids are only heated to their maximum temperatures above their equilibrium temperatures for a short period, of the order of seconds. From theCambridge English Corpus It was found that meteoroids from cometary sources were typically of porous, aggregate compositions with relatively low densities. From theCambridge English Corpus Sputtering provides a mechanism for the meteoroids to lose a substantial fraction of their momentum and energy without experiencing extreme heating. From theCambridge English Corpus This may be the reason why some large meteoroids have been observed at lower heights than expected before total ablation occurs. From theCambridge English Corpus In general, the detailed atmospheric response to the transit of a very hotmeteoroidbody is a complicated, non-equilibrium problem. From theCambridge English Corpus The majority of the kinetic energy of ameteoroidis dissipated by these processes, which are collectively known as ablation.
