A 54-pound (24.5-kg) Martian meteorite that is the largest known piece of Mars found on Earth has sold for $5.3 million at Sotheby’s, setting a new auction record for a meteorite.
The auction on Wednesday for the rock known as NWA 16788 sparked a 15-minute bidding war between online and phone bidders.
“This is an amazing Martian meteorite that broke off of the Martian surface,” said Cassandra Hatton, Sotheby’s vice-chairman and global head of science and natural history, ahead of the auction.
The fragment was discovered in November 2023 by a meteorite hunter in the Sahara Desert, in Niger’s remote Agadez region.
“The people there knew already that it was something special,” said Hatton. “It wasn’t until it got to the lab and pieces were tested that we realised, ‘Oh my gosh, it’s Martian.’ And then when those results came back and we compared and saw, OK, it’s not just Martian, it is the biggest piece of Mars on the planet.”
About 5 million years ago, an asteroid or comet slammed into Mars so hard that rocks and other debris launched into space.
“So it comes hurtling... 140m miles through space, makes it through Earth’s atmosphere,” said Hatton, noting that most things burn up in our planet’s atmosphere.
“It’s incredible that it made it through and then that it crashed in the middle of the desert instead of the middle of the ocean, in a place where we could find it, and that somebody who could recognise what it was.”
