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 ...
Diamonds so small that they contain only about 2000 carbon atoms are abundant in meteorites, and some of them formed in stars before the Solar System existed. [1] High pressure experiments suggest large amounts of diamonds are formed from methane on the ice giant planets Uranus and Neptune , while some planets in other planetary systems may be ...
Its diamond structure can be considered to be made up of interlocking rings of six carbon atoms, in the chair conformation. In lonsdaleite, some rings are in the boat conformation instead. At nanoscale dimensions, cubic diamond is represented by diamondoids while hexagonal diamond is represented by wurtzoids .
After a 4.5-billion-year journey through space, a car-size rock fell to Earth on October 7, 2008 — and it contained a bunch of tiny diamonds.
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 ...

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.
