HED meteorite

Diogenite

The HED meteorites are a group of achondrite meteorite types:[1]

  • Howardites
  • Eucrites
  • Diogenites

These are all thought to have come from the crust of the asteroid 4 Vesta. Their differences are due to different geologic histories of the parent rock. Their crystallization ages are between 4.43 and 4.55 billion years ago, by their radioisotope ratios.
