Footnotes

Vesta is the second largest asteroid and the only large one covered with basalt; the fine-grained volcanic rock makes up the dark areas of the Moon and the huge shield volcanoes on Mars. Three groups of achondrites (igneous meteorites) are widely thought to have come from Vesta; these are the HED meteorites: Howardites, Eucrites and Diogenites.
