Yamato 983589 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 983589’s official classification is CO3. The “CO3” classification denotes a carbonaceous chondrite from the CO group, particularly of petrologic type 3, characterized by small chondrules and refractory inclusions that make up about half of the rock’s volume. This type of meteorite displays a low degree of water-based alteration and is marked by a significant presence of chondrules and minerals in an unaltered state, with some low-calcium pyroxene grains showing unique twinning.

The Yamato 983589 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.
