A rare Martian meteorite, weighing a hefty 54 pounds, has shattered auction records, selling for a staggering $5.3 million, including taxes and fees, to a private buyer through Sotheby’s in New York.
Named NWA 16788, the massive space rock was discovered in November 2023 in Niger’s Agadez region. According to Sotheby’s, it’s 70% larger than the next biggest piece of Mars found on Earth and stands out as one of only around 400 Martian meteorites ever recovered.
“This is a discovery of extraordinary significance — the largest Martian meteorite ever found on Earth, and the most valuable of its kind ever offered at auction,” said Cassandra Hatton, Sotheby’s vice chairman of science and natural history. “Its immense size and unmistakable red color set it apart as a once-in-a-generation find.”
Scientists believe the meteorite was dislodged from Mars during a violent asteroid impact, which caused portions of the rock to transform into glass. That glassy texture, still visible on its crust, was further shaped as it plummeted through Earth’s atmosphere.
While some scientists voiced concern about the specimen going to a private collection, others see its sale as part of a larger ecosystem that supports space science.
“If there was no market for searching, collecting, and selling meteorites, we would not have anywhere near as many in our collections — and this drives the science,” said planetary scientist Julia Cartwright.
Even though its final home remains unknown, researchers hope the new owner will contribute to ongoing scientific exploration.
