Grosnaja

The Grosnaja meteorite fell near the city of Grozny, Russia, in 1861. It was an observed fall, which meant fresh specimens were collected and quickly distributed to various scientific institutions. This rapid recovery allowed for excellent preservation of the material.

Grosnaja is classified as a CO3 carbonaceous chondrite. This group of meteorites is known for being heavily populated with tiny, spherical silicate structures known as chondrules. They are closely related to the CV chondrites but generally have smaller inclusions.

Because it is a well-preserved CO3 chondrite, Grosnaja is used by researchers as a standard reference for understanding the geochemistry of early solar system materials. The pristine nature of its abundant small chondrules provides valuable data on planetary formation. It is one of the oldest objects scientists can physically study.

Like many historically significant meteorites recovered in the 19th century, main masses of Grosnaja are held in major museum collections, including the Russian Academy of Sciences. Small slices and fragments are also traded among private meteorite collectors. The largest portion remains in institutional hands for ongoing research.
