摘要
The comet hypothesis of the origin of lunar ice, which was recently discovered in the polar regions of the moon by Lunar Prospector, is examined. It is shown that a comet impact produces a temporary atmosphere whose volatile component. accumulates essentially completely in cold traps - the permanently shadowed regions of the Moon. The condensation of volatile compounds leads to the formation of ice with a definite chemical and isotopic composition, which contains important information about the composition of the comet: This hypothesis can be checked during the next lunar missions, and if confirmed, detinite progress will have been made in understanding the nature of comets.
