mars meteorite sothebys auction 1234747203

A 54-pound chunk of Mars, believed to be the largest Martian meteorite ever discovered on Earth, will be auctioned at Sotheby’s New York on July 16 with an estimate of $2 million to $4 million. Named NWA 16788, the meteorite was found in November 2023 in Niger’s Agadez region and accounts for 6.5 percent of all known Martian material on Earth, making it 70 percent larger than the next largest piece. Sotheby’s is billing it as the most valuable meteorite ever offered at auction, and it will be on public view from July 8–15 before the live sale.
