Kids Encyclopedia Facts

The HED meteorites are a grouping of achondrite meteorite types, the:

  • Howardites
  • Eucrites
  • Diogenites
  • Dunite
  • Olivine Diogenites

These are all thought to have originated from the crust of the asteroid 4 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.
