>Most of the meteorites on Earth are stony ones named ordinary chondrites. Two classes of these chondrites, known as H and L, make up 70 percent of all meteorite falls.
>Scientists had suspected that the L chondrites originated from a single parent asteroid. Many have mineralogical features indicating they were heavily shocked, scorched and degassed before gradually cooling, implying they were liberated from a giant asteroid — at least 100 kilometers long — via a supersonic collision.
>Using radioactively decaying elements to determine the age of the meteorites has revealed that they first emerged from a collision that happened 470 million years ago.
