What asteroid parent do most meteorites landing on earth
Which asteroid parent do most of the meteorites that land on earth come from? Which asteroid is most likely the parent of the meteorites that I find?

In regards to the most common meteorites...
The most commonly found meteorite on the surface of our planet, Earth, is known by the name "H chondrite". These are stony meteorites with a "high" (H) total iron content.
The comparisons of the reflectance spectra of the H chondrites to the
spectra of several main belt asteroids have yielded a probable parent
body - the asteroid 6 Hebe.
However, 6 Hebe might not be the direct source of the H chondrites but only some sort of ancestor. Probably 6 Hebe collided with another asteroid at one time of his history and larger parts of it were
dislodged into an elliptical near-earth orbit. The resulting swarm of
NEOs, the children of 6 Hebe, are thought to be the true parent bodies from which the H chondrites are derived.

Thanks for taking the time... very cool to know about this. I have collected about a kilo of meteorites now and I have looked a lot of places trying to find this out. I really appreciate it! Deb
