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 nearside.
The largest fragment weighs over 2 kg (4.4 lb), and the smallest weighs about 45 g (1.6 oz). The larger pieces show a black-brown partial fusion crust, caused by the heat generated as the meteorite descended through Earth's atmosphere. The large pieces also show thumb printing. Internally, the breccia is fragmented, with white clasts of ...
During this year’s event, the moon will be 95% full on Thursday night into Friday, which will obscure at least 75% of the activity seen in years with little to no moonlight, according to the ...

They streak through the sky at a speed of 22 miles per second. Meteors are space rocks that enter Earth's atmosphere and heat up as they fall toward Earth, according to NASA. The streak of light ...
The NASA astronauts who became the first people to land on the moon's surface in the 1960s and 1970s also discovered a previously unknown lunar characteristic - it has an atmosphere, though quite ...
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.
Evidence that ALHA 81005 is a lunar sample, was presented at the 18 March 1983 meeting of the Lunar and Planetary Institute. The evidence included fabric data, mineralogical data, compositional data, oxygen isotope data, noble gas data, cosmic ray exposure history, magnetic properties , nuclear particle tracks, and thermoluminescence data.
