Martian Meteorite to Fetch Millions at New York Auction

A remarkable sale is on the horizon for space enthusiasts: a 54-pound meteorite is anticipated to bring in between $2 million and $4 million at auction. The fascinating aspect? It stands as the most sizable fragment from Mars ever discovered on our planet.

Sotheby's in New York is set to auction this celestial marvel, designated NWA 16788, amid an array of natural history items. This collection also features an impressive juvenile Ceratosaurus skeleton.

The auction house reports that this meteorite's journey began with an enormous asteroid impact on Mars, which sent it hurtling 140 million miles until it landed in the Sahara Desert. Found by a meteorite hunter in Niger in late 2023, this rock is a unique find.

Boasting shades of red, brown, and gray, the piece is significantly larger than any other Martian sample found on Earth to date, adding up to almost 7% of all Martian material ever located here. Its dimensions are substantial, measuring close to 15 by 11 by 6 inches.

In an interview, Cassandra Hatton, Deputy Chair for Science and Natural History at Sotheby's, highlighted its significance. 'This meteorite from Mars is the largest we have ever found, far exceeding previous examples in size,' she remarked.

This is indeed a rare discovery, notes Sotheby's, as there are only about 400 known Martian meteorites among more than 77,000 meteorites officially recorded on Earth.

To verify its origins, a fragment of the meteorite was sent to a specialized laboratory. Analysis confirmed its Martian past, matching its unique chemical makeup—similar to those studied by the Viking probe that reached Mars in 1976.

Classified as an 'olivine-microgabbroic shergottite,' this type of Martian rock forms from the gradual cooling of lava on Mars. Sotheby's elaborates that it contains minerals such as pyroxene and olivine.

The rock's glassy exterior likely results from the intense heat experienced upon entering Earth's atmosphere, Hatton explained, having sparked initial interest due to its unusual surface.

Before arriving at Sotheby's, this cosmic artifact had been displayed at the Italian Space Agency in Rome. Details about the current owner remain undisclosed.

Although the exact timing of its Earthfall is uncertain, examinations suggest it occurred not too long ago, according to Sotheby's.
