The Sutter's Mill meteorite is a carbonaceous chondrite which entered the Earth's atmosphere and broke up at about 07:51 Pacific Time on April 22, 2012, with fragments landing in the United States. [ 6 ] [ 7 ] The name comes from Sutter's Mill , a California Gold Rush site, near which some pieces were recovered.

This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors.
The Gold Rush began in earnest in 1849, which led to its eager participants being called "49ers," and within two years of James Marshall's discovery at Sutter's Mill, 90,000 people flocked to ...
