Where do meteorites come from? For years, planetary scientists have puzzled over this problem, for almost no known asteroids matched the composition of the most common rocky meteorites, the ordinary chondrites. Now new analyses of the color (and therefore the composition) of the asteroid Hebe suggest that this single body may contribute up to half the known chondrites.
