Recommended classes in the Meteoritical Bulletin Database are assigned by the database editor. © The Meteoritical Society

The recommended classification Howardite means:

" An achondrite from the howardite group."

The highlighted words are defined as follows:

Achondrite: A stony meteorite that lacks chondrules and originated on a differentiated parent body.

Howardite: Howardites are an abundant group of polymict-breccia achondrites that appear to represent mixtures of eucrites + diogenites (these three linked groups are collectively known as HED meteorites and may come from asteroid 4 Vesta). The main minerals in howardites are pyroxene (largely orthopyroxene) and Na-poor plagioclase. A minority of howardites are rich in solar-wind noble gases and thus inferred to be regolith breccias.
