Abstract This paper shows morphological similarity between aggregates separated from the lunar regolith ultra-fine size fraction and interplanetary dust particles (IDPs) collected in Earth’s stratosphere. It also demonstrates morphological difference between mentioned above and cometary particles from comet Wild 2 collected in the “Stardust” project. Given the number of lunar meteorites found on Earth, the Moon’s proximity to Earth, and its large surface area subject to high energy meteoroid impacts, makes it highly likely that all size spectrum of material ejected from lunar surface may have been grazed by Earth.

月球尘埃粒子与从地球大气层收集的行星际尘埃粒子之间可能的形态相似性

摘要 本文显示了从月球风化层超细粒度部分分离的聚集体与地球平流层中收集的行星际尘埃粒子 (IDP) 之间的形态相似性。它还证明了上述与“星尘”项目中收集的来自彗星Wild 2的彗星粒子之间的形态差异。考虑到在地球上发现的月球陨石数量、月球与地球的距离以及它受高能流星体撞击的大表面积，从月球表面喷出的所有尺寸的物质都有可能被地球擦过。
