How many other observed aubrite falls are known globally besides the 2024 BX1 event?
Answer
11
The scarcity of the aubrite subclass, an achondrite type, is extremely pronounced, particularly when focusing only on documented falls. Following the recovery of fragments from asteroid 2024 BX1 over Berlin, it was noted that material from only 11 other observed aubrite falls had been recorded and cataloged in meteorite collections worldwide up to that point. This small historical count highlights the statistical rarity of this specific type of rock surviving atmospheric entry and being witnessed by observers. Aubrites are significant because they formed from parent bodies that underwent substantial melting, which resulted in the distinct lack of chondrules, the universal round mineral inclusions found in more primitive meteorites.
