The biggest piece of Mars on Earth is going up for auction in New York

Boston Globe2 days ago
The red, brown and gray hunk 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).

'This Martian meteorite is the largest piece of Mars we have ever found by a long shot,' Cassandra Hatton, vice chairman for science and natural history at Sotheby's, said in an interview. 'So it's more than double the size of what we previously thought was the largest piece of Mars.'

It is also a rare find. There are only 400 Martian meteorites out of the more than 77,000 officially recognized meteorites found on Earth, Sotheby's says.
Hatton said a small piece of the red planet remnant was removed and sent to a specialized lab that confirmed it is from Mars. It was compared with the distinct chemical composition of Martian meteorites discovered during the Viking space probe that landed on Mars in 1976, she said.

The examination found that it is an 'olivine-microgabbroic shergottite,' a type of Martian rock formed from the slow cooling of Martian magma. It has a course-grained texture and contains the minerals pyroxene and olivine, Sotheby's says.
It also has a glassy surface, likely due to the high heat that burned it when it fell through Earth's atmosphere, Hatton said. 'So that was their first clue that this wasn't just some big rock on the ground,' she said.
The meteorite previously was on exhibit at the Italian Space Agency in Rome. Sotheby's did not disclose the owner.
It's not clear exactly when the meteorite hit Earth, but testing shows it probably happened in recent years, Sotheby's said.
The juvenile Ceratosaurus nasicornis skeleton was found in 1996 near Laramie, Wyoming, at Bone Cabin Quarry, a gold mine for dinosaur bones. Specialists assembled nearly 140 fossil bones with some sculpted materials to recreate the skeleton and mounted it so it's ready to exhibit, Sotheby's says.
The skeleton is believed to be from the late Jurassic period, about 150 million years ago, Sotheby's says. It's auction estimate is $4 million to $6 million.
Ceratosaurus dinosaurs were bipeds with short arms that appear similar to the Tyrannosaurus rex, but smaller. Ceratosaurus dinosaurs could grow up to 25 feet (7.6 meters) long, while the Tyrannosaurs rex could be 40 feet (12 meters) long.
The skeleton was acquired last year by Fossilogic, a Utah-based fossil preparation and mounting company.

Wednesday's auction is part of Sotheby's Geek Week 2025 and features 122 items, including other meteorites, fossils and gem-quality minerals.

At 54 pounds, this Mars rock is largest on Earth. It could sell at auction for $4 million

Sotheby's in New York City will auction off a cosmic item billed as the largest Martian meteorite ever found on Earth on July 16, 2025. A chunk of the Martian surface that made an unlikely interplanetary voyage to Earth will soon be available to the highest bidder. And for a few million dollars, it could be yours. Sotheby's, a British-founded broker based in New York City, will soon auction off a cosmic item it's billing as the largest Martian meteorite ever found on Earth. Of course, such a distinction is expected to also fetch a high price tag. Here's everything to know about the large, valuable Mars rock. Mars rock could sell for $4 million at Sotheby's auction in New York The large space rock, which has the scientific name of NWA 16788, had its Martian origins validated by the Meteoritical Society, which included it in its Meteoritical Bulletin, the global journal of record for meteor-related science. Sotheby's, one of the oldest and largest fine auctioneers of art and collectibles in the world, will auction off the meteorite, along with more than 100 other items, Wednesday, July 16, at its New York City headquarters. Marketed by Sotheby's as "the largest Martian meteorite ever found on Earth," the cosmic object could sell for up to $4 million, making it the most valuable meteorite ever offered at auction. "NWA 16788 is a discovery of extraordinary significance," Cassandra Hatton, vice chairman of science and natural history for Sotheby's, said in a statement. "Weathered by its journey through space and time, its immense size and unmistakable red color sets it apart as a once-in-a-generation find." What are meteorites? Rocks in space are known as meteoroids. If those space rocks enter Earth's atmosphere, they become meteors that streak across the sky in events colloquially referred to as "shooting stars." Meteors – or fragments of them – that survive their atmospheric trip and land on the surface without burning up become meteorites, according to NASA. Martian meteorite, or Mars rock, is largest on Earth: How big is it? The Martian meteorite is 54 pounds, or about the weight of a standard bag of cement. Measuring nearly 15 inches by 11 inches by 6 inches, the space rock is approximately 70% larger than the next largest piece of Mars found on Earth. In fact, it is so large that it represents approximately 6.5% of all Martian material ever found on Earth. How did Martian space rock get to Earth? NWA 16788 was discovered Nov. 16, 2023, by a meteorite hunter in Niger's remote Agadez region in the Sahara Desert. Featuring an unmistakable reddish Martian hue, NWA 16788's internal composition suggests it was blasted from the surface of Mars by a powerful asteroid strike. Intense enough to turn some of the meteorite's minerals into glass, the asteroid strike sent the rock hurtling through space, where it miraculously made it through Earth's atmosphere without burning up, Sotheby's said in an auction house video. Because the meteorite shows signs of minimal Earthly weathering, and its chemical makeup has not significantly changed, experts believe it reached our planet in recent years. On a planet mostly covered in water, discovering meteorites on land is incredibly rare. And Mars meteorites are even more elusive on Earth. Of the more than 77,000 officially recognized meteorites, only 400 are Martian meteorites, according to Sotheby's. The meteorite was previously on exhibit at the Italian Space Agency in Rome and at a private gallery in Arezzo, Tuscany before it landed in Sotheby's auction.

The biggest piece of Mars on Earth is being auctioned off in New York

A 25-kilogram rock is being auctioned off at Sotheby's New York on Wednesday. It's being listed for a price of $2 million (€1.71 million) to $4 million (€3.42 million). Why so expensive? Well, it's not just any rock. It's the largest piece of Mars ever found on Earth. The Martian rock, known as NWA 16788, will be sold as part of a natural history-themed sale that also includes a juvenile Ceratosaurus dinosaur skeleton that's more than 2 metres tall and nearly 3 metres long. According to the auction house, the meteorite is believed to have been blown off the surface of Mars by a massive asteroid strike before traveling 225 million kilometres to Earth, where it crashed into Africa's Sahara Desert. A meteorite hunter found it in the remote Agadez Region of Niger in November 2023, Sotheby's says. The reddish-brown hunk 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, measuring in at nearly 375 millimetres in length, 279 millimetres in width and 152 millimetres in height. 'This Martian meteorite is the largest piece of Mars we have ever found by a long shot," said Cassandra Hatton, vice chairman for science and natural history at Sotheby's. 'So it's more than double the size of what we previously thought was the largest piece of Mars.' The rock is a super a rare find. There are only 400 Martian meteorites out of the more than 77,000 officially recognised meteorites found on Earth, Sotheby's says. Hatton asserted that a small piece of it was removed to study it and confirm that it is indeed Martian. The study found that it is an 'olivine-micro gabbroic shergottite,' formed from the slow cooling of Martian magma. It has a course-grained texture composed primarily of pyroxene, Maskelynite, and olivine, Sotheby's says. It also has a glassy surface, likely due to the high heat that burned it when it fell through Earth's atmosphere, Hatton said. 'So that was their first clue that this wasn't just some big rock on the ground,' she said. It's not clear exactly when the meteoroid hit Earth, but testing shows it probably happened in recent years, Sotheby's said. Also on auction is the juvenile Ceratosaurus skeleton, which was found in 1996 near Laramie, Wyoming in the United States at Bone Cabin Quarry – a gold mine for dinosaur bones. Specialists assembled nearly 140 fossil bones with some sculpted materials to recreate the skeleton and mounted it so it's ready to exhibit. The skeleton is believed to be from the late Jurassic period, about 150 million years ago, Sotheby's says. It's auction estimate is anywhere between $4 million (€3.42 million) to $6 million (€5.13 million). It's unclear if the items will actually sell at these prices, as such items have never been sold at auction before. Sotheby's says whoever ends up purchasing the incredibly rare items is guaranteed to snag a one of a kind piece of history.
