More Details About the Yamato 790490 Meteorite
The Yamato 790490 meteorite was discovered in 1979. It was recovered in Antarctica (-71.5, 35.66667). It has a mass of 1.18 grams.
Yamato 790490 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 790490’s official classification is E. The “E” classification refers to a type of meteorite known as an enstatite chondrite, which is characterized by its unique mineral compositions, such as having magnesium-to-silicon ratios near the solar value and specific oxygen isotope compositions. This particular meteorite, however, has not been assigned to any specific group or petrologic type within the enstatite chondrites, indicating that its detailed classification is yet to be determined.
The Yamato 790490 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.
