Largest piece of Mars on Earth fetches meteoric $5.3 million at New York auction

The largest piece of Mars ever found on Earth was sold for just over $5 million at an auction of rare geological and archaeological objects in New York on Wednesday, while a juvenile dinosaur skeleton went for more than $30 million.

The 54-pound (25-kilogram) rock named NWA 16788 was discovered in the Sahara Desert in Niger by a meteorite hunter in November 2023, after having been blown off the surface of Mars by a massive asteroid strike and traveling 140 million miles (225 million kilometers) to Earth, according to Sotheby’s. The estimated sale price before the auction was $2 million to $4 million.

The identity of the buyer was not immediately disclosed. The final bid was $4.3 million. Adding various fees and costs, the official bid price was about $5.3 million.

Two advance bids of $1.9 million and $2 million were submitted. The live bidding went slower than for many other objects that were sold, with the auctioneer trying to coax more offers and decreasing the $200,000 to $300,000 bid intervals to $100,000 after the proposals hit $4 million.

The red, brown and gray meteorite is about 70% larger than the next largest piece of Mars found on Earth and represents nearly 7% of all the Martian material currently on this planet, Sotheby’s says. It measures nearly 15 inches by 11 inches by 6 inches (375 millimeters by 279 millimeters by 152 millimeters).
