Most lunar meteorites are launched from the Moon by impacts making lunar craters of a few kilometers in diameter or less. [6] No source crater of lunar meteorites has been positively identified, although there is speculation that the highly anomalous lunar meteorite Sayh al Uhaymir 169 derives from the Lalande impact crater on the lunar ...
During the 1960s, rectified images of Mare Orientale by Gerard Kuiper at the Lunar and Planetary Laboratory gave rise to the notion of it being an impact crater. [3] [4] The structure, with the flat plain of the mare in the center, is about 900 kilometres (560 mi) across and was formed by the impact of an asteroid-sized object, [5] [6] possibly 64 km (40 mi) in diameter and travelling at 15 km ...

The moon has been constantly bombarded by meteorites - early in its history by large ones that gashed the gaping craters visible on the lunar surface and more recently by smaller ones including ...

Yamato 791197, official abbreviation Y-791197, is a meteorite that was found in Antarctica on November 20, 1979. [3] It is the first lunar meteorite to be found on Earth, but was not identified as such until 1984, after the lunar origin of ALH 81005 was recognised. [4] It was collected by the National Institute of Polar Research, Japan. [1]
This is a list of largest meteorites on Earth. Size can be assessed by the largest fragment of a given meteorite or the total amount of material coming from the same meteorite fall: often a single meteoroid during atmospheric entry tends to fragment into more pieces. The table lists the largest meteorites found on the Earth's surface.
A lunar lava cave potential has long been suggested and discussed in literature and thesis. [27] Any intact lava tube on the Moon could serve as a shelter from the severe environment of the lunar surface, with its frequent meteorite impacts, high-energy ultraviolet radiation and energetic particles, and extreme diurnal temperature variations.
