A 54-pound Martian meteorite, officially named Northwest Africa 16788 (NWA 16788), was discovered in Niger’s Sahara Desert in November 2023. On July 16, 2025, Sotheby’s in New York sold the rock at auction for a final bid of $4.3 million, which, after fees, totaled approximately $5.3 million, making it:
– The largest known piece of Mars ever found on Earth.
– Representing nearly 7% of all Martian material on our planet .
Laboratory analysis confirmed the meteorite is an “olivine-microgabbroic shergottite,” matching chemical signatures from NASA’s 1976 Viking Mars mission . With only about 400 Mars-origin meteorites identified out of over 77,000 total meteorites discovered, this specimen is exceptionally rare .
Cassandra Hatton, Sotheby’s vice-chairman for science and natural history, highlighted the meteorite’s prominence and its intact condition, which suggests it fell to Earth recently .
The sale was part of Sotheby’s Geek Week 2025, held at the American Museum of Natural History, and featured alongside a juvenile Ceratosaurus dinosaur skeleton that fetched $30.5 million . Debate continues over private versus institutional ownership of such rare scientific treasure.
Why does this Matter?
This meteorite offers a rare geological snapshot of Mars and could provide invaluable scientific insight.
Its historic sale—dramatically surpassing the estimated $2 – 4 million range—reflects growing public and private interest in extraterrestrial material.
Raises important questions about balancing scientific accessibility with private collecting.
