485999

485999 is a numerical code that has been identified as the 64th most common meteorite fall with a reported fall in Arizona, United States, in 1911. The meteorite is believed to have originated from the asteroid belt between the orbits of Mars and Jupiter. Weighing approximately 35.8 kilograms, the Sutter's Mill meteorite is classified as a stony-iron meteorite, meaning it is primarily composed of metal and has a stony outer layer.

The Sutter's Mill meteorite was found on August 1, 1911, near the town of Georgetown, on the American River in California. The meteorite was later identified as falling from the sky, with the first reports suggesting it had a rough, lumpy texture.

Analyses have revealed Sutter's Mill to be of L3 chondrite type with a metal fraction of roughly 16%, and averages a whole-rock density of around 5.0 g/cm3. Notably, ingots made from the meteorite have displayed little to no observed heat treatment effects on its outer layers, implying little interference of external energy on its bulk structure.

Today, the Sutter's Mill meteorite continues to be of great interest to the scientific community, providing valuable information into the history of the universe and further understanding of the physical characteristics of meteorites in general.
