Sotheby’s in New York is set to auction the largest known piece of Mars ever found on Earth—a 54-pound (24.67 kg) meteorite named NWA 16788.
Scientists say the meteorite likely blasted off Mars after a massive asteroid impact and travelled 140 million miles before landing in the Sahara Desert. It was discovered in Niger in November 2023 by a meteorite hunter.
A small sample was sent for lab testing, confirming its Martian origin by comparing its chemical makeup with meteorites collected by NASA’s Viking landers in 1976.
The rock is classified as an olivine-microgabbroic shergottite, formed from slow-cooling Martian magma and featuring minerals like pyroxene and olivine. Its glassy surface shows it endured intense heat entering Earth’s atmosphere.
The meteorite was previously exhibited at the Italian Space Agency in Rome, though its current owner remains undisclosed. Testing suggests it fell to Earth only in recent years.
Alongside the meteorite, Sotheby’s Geek Week auction on 16 July will feature a mounted juvenile Ceratosaurus dinosaur skeleton, estimated at $4 to $6 million. The skeleton, from the Late Jurassic period about 150 million years ago, was discovered in Wyoming in 1996 and reassembled by fossil experts.
The Ceratosaurus, a bipedal predator smaller than the Tyrannosaurus rex, could grow up to 25 feet long. This specimen stands more than 6 feet tall and nearly 11 feet long.
The auction includes 122 lots, ranging from meteorites and fossils to gem-quality minerals, showcasing some of the rarest natural history treasures on the market today.
