H Group

This large group counts more than 7.000 members (including lots of probable pairings), and it has been named for the high content of free nickel-iron that is characteristic for the meteorites of this group - the "H" standing for "high iron". H chondrites contain a weight percentage of 25 to 31% total iron whereas only 15 to 19% nickel-iron is found in its free, reduced form. Hence, all H chondrites are attracted to a magnet quite easily.

The H chondrites belong to petrological types 3 - 7, with a characteristic peak at type 5. More than 3,400 members of this group have been classified as H5, about 1,800 are H6, and about 1,400 are H4. There are only about 200 H3s as well as some rare, heavily brecciated members that contain lithic clasts of several petrological types. The primary minerals are olivine and the orthopyroxene bronzite. For this reason the H chondrites have also been called "olivine bronzite chondrites" or "bronzite chondrites", but those names are no longer in use.

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
