Sotheby's is auctioning a 15x11x6 inch Martian meteorite in New York, estimated at $2-$4 million. This is the largest Martian meteorite ever found on Earth, weighing in at nearly 7% of all known Martian material on our planet. Discovered in Niger in November 2023, it's believed to have originated from a Martian asteroid impact and traveled 140 million miles to Earth.
