? A Piece of Mars Lands on Earth—and in Auction History

A rare Martian meteorite, named NWA 16788, was sold for a record-breaking $5.3 million at Sotheby’s ‘Geek Week’ auction in New York on July 16, 2025. This 24.67 kg (54 lb) space rock sets a new benchmark in extraterrestrial sales.

Key Facts & Stats

• Name: Northwest Africa 16788 (NWA 16788)
• Weight: 24.67 kg (54 lb), ~70% larger than the next-largest Martian fragment 1
• Color & Composition: Distinct deep‑red hue, glassy crust, contains volcanic minerals like pyroxene and olivine 2
• Discovery: Found in November 2023 in Niger’s Agadez region of the Sahara Desert 3
• Journey: Ejected from Mars by asteroid impact ~5 million years ago; traveled ~225 million km 4

Why It Matters

With fewer than 400 known Martian meteorites on Earth, NWA 16788 offers scientists one of the largest and most pristine Martian samples available—especially vital after NASA’s Mars Sample Return delay 5. Its minimal terrestrial weathering suggests a recent Earth impact 6.

Auction Highlights

Initially estimated at $2–4 million, bidding soared during a fierce 15-minute contest among online and phone bidders, ending at $4.3 million hammer price plus fees, totaling approximately $5.3 million 7. It now stands as the most expensive meteorite ever sold.

Trivia & Timeline
