Eltanin, the largest meteorite of which intact fragments are preserved

Location: Geology 3656
Time: 2:30PM

The largest recovered meteorite was discovered at the bottom of the Pacific Ocean about 1500 km west of the southern tip of South America. It has been documented by sediment cores collected during a series of German oceanographic cruises. About 2.5 million years ago a one-kilometer-diameter asteroid impacted the ocean and deposited more than one kilogram of meteorites per square meter over thousands of square kilometers. About 90% of this was melted by the shock of the impact, but 10% is undamaged meteorite fragments.
