It was the second meteorite to be discovered on a Solar System body other than the Earth.
The first was the Bench Crater meteorite, discovered in 1969 during the Apollo 12 mission.
Within the soil sample 15602,29 collected near Hadley Rille was found an object in the 1–2 millimetres (0.039–0.079 in) size.
The Hadley Rille meteorite massed about 3 milligrams (0.046 gr) and contained enstatite, kamacite, niningerite, silica, schreibersite, troilite, albite, and daubréelite.
It is classed as an enstatite chondrite (EH) by the Meteoritical Society.
