Sotheby’s 'NWA 16788,' is a 54-lb (24.67-kg) specimen recognized as the largest known piece of Mars on Earth. The rock, featuring minerals partially transformed into glass from an extreme asteroid impact, was discovered in 2023 in Niger’s remote Agadez region of the Sahara Desert. Classified among just a few hundred verified Martian meteorites, it represented a rare opportunity for collectors focused on planetary science memorabilia.
The meteorite was offered during Sotheby’s 2025 “Geek Week” marquee science auction series, which spotlights high-profile scientific artifacts. Pre-sale estimates ranged from US$2 million to US$4 million, with online bidding reaching US$1.92 million, including buyer’s premium, nearly two weeks before the scheduled close. According to the auction house, the lot ultimately achieved a hammer price of US$4.3 million, with fees bringing the official total to US$5.3 million.
