Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge. In general, 0.1\u20131-m sized meteoroids do not arrive on similar orbits as the larger ~1-km sized near-Earth asteroids (NEA) of corresponding taxonomic class. Unlike larger NEA, a group of H chondrite meteoroids arrived on low-inclined orbits from a source just beyond the 5:2 mean-motion resonance with Jupiter (N\u2009=\u200912), three of which have the 7\u2009Ma cosmic ray exposure (CRE) age from a significant collision event among H chondrites. There is also a source of H chondrites low in the inner main belt with a ~35\u2009Ma CRE age (N\u2009=\u20098). In contrast, larger H-like taxonomic S-class NEA arrive from high-inclined orbits out of the 3:1 resonance. Some H chondrites do so also, four of which have a 6\u2009Ma CRE age and two have an 18\u2009Ma CRE age. L chondrites arrive from a single source low in the inner main belt, mostly via the \u03bd6 secular resonance (N\u2009=\u200921), not the 3:1 resonance as most L-like NEA do. LL chondrites arrive too from the inner main belt (N\u2009=\u20095), as do larger LL-like NEA. CM chondrites are delivered from a low i\u2009&lt;\u20093\u00b0 inclined source beyond the 3:1 resonance (N\u2009=\u20094). Source asteroid families for these meteorite types are proposed, many of which have the same CRE age as the asteroid family&#8217;s dynamical age. Also, two HED achondrites are now traced to specific impact craters on asteroid Vesta.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Peter Jenniskens, Hadrien A. R.
