More Details About the Yamato 8408 Meteorite

The Yamato 8408 meteorite was discovered in 1984. It was recovered in Antarctica (-71.5, 35.66667). It has a mass of 0.02 grams.

Yamato 8408 is considered a “Valid” meteorite. “Valid” meteorites are typical meteorites with average weathering, while “relict” meteorites are those that have been extremely altered, either due to weathering over time or human intervention.

Yamato 8408’s official classification is E5. The E5 meteorite classification refers to an enstatite chondrite, a type of meteorite known for its unique chemical composition with less magnesium and silicon compared to solar values, and its formation close to the early Sun, that is classified as petrologic type 5. This indicates the meteorite has undergone significant metamorphism, leading to uniform mineral compositions, the transformation of certain minerals, the development of new minerals, and the blurring of its original chondritic features, yet it hasn’t been placed into a specific subgroup within enstatite chondrites.

The Yamato 8408 meteorite is a “Found” meteorite. Meteorites are classified as “falls” if they were observed falling and recovered, while “finds” are those discovered later, often weathered by longer exposure to Earth’s environment and without a record of being seen as they fell.
