Christie’s Auction House has a chunk of the moon for sale, and it’s valued at $2.5 million. The lunar meteorite (designated formally as NWA 12691) weighs about 30 pounds, and it was discovered in the Sahara desert in 2017. It is exceedingly rare for a moon rock this big to be up for sale.

Christie’s notes that this is the fifth-largest specimen known on Earth, and this one is larger than any brought back by astronauts. The private sale began last week. “The experience of holding a piece of another world in your hands is something you never forget,” says the auction house’s resident science expert.
