Meteorite Rarity
Meteorites are extraordinarily rare on a planet-wide scale. Lunar and Martian meteorites are scarcer than almost any natural material a collector can buy: every approved lunar meteorite on record adds up to about two metric tons, and every Martian meteorite to about 416 kilograms.

How Many Meteorites Exist on Earth?
The Meteoritical Bulletin Database lists 80,603 approved meteorites as of October 2026. Each one has been recovered, scientifically analyzed, and officially named by the Nomenclature Committee of the Meteoritical Society. That number grows by roughly 1,000 to 2,000 entries each year, primarily from Antarctic and hot-desert recovery programs.
Although 80,000 may sound like a large number, it is small in absolute terms. Most of their combined mass sits in a few hundred giant iron meteorites. By our count of the database in October 2026, the 868 heaviest approved meteorites add up to about 680 metric tons, and the ten heaviest alone, led by Aletai (74 tonnes recorded) and Hoba (60 tonnes), account for about 390 metric tons. For comparison, about 3,300 metric tons of gold were mined worldwide in 2025, according to the US Geological Survey.
Rarity by Meteorite Type
Within the global catalog, certain meteorite types are vastly rarer than others. The numbers below reflect approximate proportions in the current classified inventory.
Why Lunar and Martian Meteorites Are So Rare
The rarity of lunar and Martian meteorites is a function of orbital mechanics. To send a rock from the Moon or Mars to Earth, an impactor must strike the parent body hard enough to launch material above the local escape velocity. From the Moon, that requires a speed greater than 2.4 km/s. From Mars, it requires more than 5 km/s, against a gravitational well that is much deeper and against a thin atmosphere that further slows ejecta.
Only a small fraction of large impact events produce material that escapes, and only a small fraction of that material is eventually swept up by Earth's gravity. The journey itself can take millions of years, and the surviving fragments are typically small. Most lunar meteorites and Martian meteorites recovered to date weigh under 1 kilogram.
The recorded masses of all approved lunar meteorites add up to about 2,031 kilograms, a little over two metric tons. Martian meteorites total about 416 kilograms. Both figures come from the Meteoritical Bulletin Database as of October 2026 and count database entries, so paired fragments of one fall are listed separately. By comparison, about 3,300 metric tons of gold were mined worldwide in 2025, according to the US Geological Survey. A single year of gold mining outweighs every known Martian meteorite about 8,000 times over, and every known lunar meteorite more than 1,600 times over.
Typical retail prices run from about $45 to more than $1,000 per gram for lunar meteorites and from about $75 to more than $5,000 per gram for Martian meteorites, depending on type, size and documentation. Gold traded at about $129 per gram in late October 2026, so planetary meteorites range from below the price of gold to many times above it, gram for gram. Their scarcity is far greater than that of gold; their prices reflect collector demand as well as how little exists. Current ranges are set out in how much do meteorites cost.
Witnessed Falls: A Special Category of Rarity
An entirely separate dimension of rarity is the difference between a "find" (a meteorite recovered by hunters but not seen to fall) and a "fall" (a meteorite observed entering the atmosphere and recovered shortly afterward).
Only about 1,300 witnessed falls have been documented in all of recorded history. Each one carries a unique scientific value because there is no terrestrial weathering between the fall and the recovery, which preserves the original composition for laboratory analysis. Famous historical falls include Ensisheim (1492), Pultusk (1868), Allende (1969), Murchison (1969), Sikhote-Alin (1947), and Chelyabinsk (2013).
Within the collector market, a documented fall typically commands a substantial premium over a find of the same classification, particularly if the specimen comes with provenance materials such as recovery photos, fall reports, or original collector documentation.
Meteorites are far scarcer than gold, and unlike gold, diamonds or rubies, no future technology can produce more of them. They exist only in the small quantities the solar system has happened to deliver.
Why Meteorites Will Always Be Rare
Unlike most rare materials on Earth, meteorites cannot be created, manufactured, or replenished. New ones arrive only at the rate the solar system delivers them, and most are lost to oceans, jungles, weathering, or simple invisibility. Recovery programs in Antarctica and the hot deserts are extraordinarily productive, but they are essentially mining the accumulated falls of tens to hundreds of thousands of years.
This means the world's meteorite supply is effectively fixed in the short term and grows only slowly over time. Collector demand, by contrast, continues to rise. Authentic, well-documented meteorites have appreciated steadily for decades, and the rarest categories (lunar, Martian, certain irons with unique compositions, classified pallasites) have appreciated more rapidly.
The rarity is also categorical. A new gold deposit can be mined; a new diamond can be cut; a new ruby can be heat-treated. But there will never be a new Allende meteorite, a new Murchison, or a new fall from the famous Pueblito de Allende that arrived in February 1969. Each meteorite represents a one-time event, and once the specimens are in collections, they are functionally all that will ever exist of that fall.

Frequently Asked Questions
How rare are meteorites really?
Extremely rare. The Meteoritical Bulletin Database lists 80,603 approved meteorites as of October 2026, and most of their combined mass sits in a few hundred giant iron meteorites. By comparison, about 3,300 metric tons of gold are mined every year.
Are lunar meteorites rarer than gold?
Yes, by an enormous margin. The recorded masses of all approved lunar meteorites add up to about 2,031 kilograms, as listed in the Meteoritical Bulletin Database in October 2026. About 3,300,000 kilograms of gold were mined worldwide in 2025, so a single year of gold mining outweighs every known lunar meteorite more than 1,600 times over.
How many Martian meteorites are there?
The Meteoritical Bulletin Database lists 435 Martian entries as of October 2026, 433 of them under approved names, with recorded masses totalling about 416 kilograms. That is a count of database entries, and many are paired fragments of the same fall. Until samples are returned by future Mars missions, these meteorites are the only physical pieces of Mars available for study on Earth.
What is the rarest type of meteorite?
Martian meteorites are usually considered the rarest broadly available category. Within Martian meteorites, ungrouped or paired specimens with unique compositions (such as NWA 7034 "Black Beauty") are rarer still. Certain unique iron and pallasite types, and some carbonaceous chondrites, are also extraordinarily scarce.
Will meteorites become even rarer over time?
Yes, in the practical sense. New falls add only a small number of recoverable specimens each year, while existing meteorites accumulate in museum and collector hands. The supply available on the open market tends to shrink as significant specimens leave the market for institutional collections.
