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)
