The largest known Martian meteorite, NWA 16788, weighing 24.67 kilograms, will be auctioned at Sotheby's New York on July 16, 2025. This remarkable specimen is approximately 70% larger than the previous record-holder.
Discovered in Niger in November 2023, NWA 16788 is one of only about 400 Martian meteorites found on Earth. Scientific analysis confirms its Martian origin and minimal terrestrial weathering.
The auction raises questions about access for research versus private ownership. This event offers unprecedented insights into Mars' geological history.
