HED meteorites are a clan (subgroup) of achondrite meteorites.
HED stands for "howardite–eucrite–diogenite".
These achondrites came from a differentiated parent body and experienced
extensive igneous processing not much different from the magmatic rocks
found on Earth and for this reason they closely resemble terrestrial igneous rocks.

Origin:

These are all thought to have originated from the crust of the asteroid Vesta,
their differences being due to different geologic histories of the parent rock.
Their crystallization ages have been determined to be between 4.43 and 4.55 billion years from radioisotope ratios.
HED meteorites are differentiated meteorites, which were created by igneous processes in the crust of their parent asteroid.
