Meteorite Density
(Densities of Meteorites by Classification)

The density of a meteorite can tell us a lot about a particular specimen. Because many types of meteorites contain a high level of metal (e.g. Iron & Nickel) they will generally be significantly heavier than common Earth rocks. Below is a list of meteorite densities for an array of various classifications. In some cases where it was not possible to determine the porosity of a meteorite, the average grain density of the meteorites' minerals is used instead of the overall bulk density. Grain densities are a little larger than the bulk densities as they do not take into account the porosity of the specimens.

This information has been compiled from an extract (METEORITE POROSITIES AND DENSITIES: A REVIEW OF TRENDS IN THE DATA. - 2108) presented at the 35th Lunar and Planetary Science Conference by D.T. Britt and G.J. Consolmagno. The full extract is available at the bottom of the page as a PDF file. Full and complete credit for the data presented in the following tables goes to the above mentioned authors of the extract.

All densities are measured in grams per cubic centimetre. (g/cm3)
An asterisk (*) denotes a grain density measurement.
