**Values presented in brackets represent the approximate known mass of the type or classification in kilograms and the percent that represents of the total known mass of meteorites. These values are approximate and presented only as a guide for estimating comparative scarcity; other factors can apply. They do not include the Antarctic meteorites, which are owned by the governments funding the researchers who find the specimens nor do they include the recent North West Africa finds. Additionally, lunar meteorites are not yet represented in this listing.
