Yamato 983789 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 983789’s official classification is H4. The classification “H4” refers to a type of ordinary chondrite meteorite from the H group that is at petrologic type 4. These meteorites are characterized by having a significant number of chondrules and have undergone metamorphism that changed the composition of minerals like olivine and pyroxene while lacking primary igneous chondrule glass. This classification helps scientists study the history and properties of meteorites, shedding light on the early solar system.

The Yamato 983789 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.
