historia: Hraschina meteorite

Evidence: 100 • authority: 72

Hraschina is the official name of an iron meteorite that fell in 1751 near the village of Hrašćina in Hrvatsko Zagorje, Croatia. This meteorite is important because it was the first fall of an iron meteorite viewed and reported by a significant number of witnesses, despite its low remaining total known weight. The Hraschina meteorite also proved that rocks really can "fall from the skies".

The First Instrumentally Documented Fall of an Iron Meteorite: Orbit and Possible Origin. Abstract A bright fireball observed on 2020 November 7, over Scandinavia, produced the first iron meteorite with a well-determined pre-atmospheric trajectory. We calculated the orbit of this meteoroid and found that it demonstrates no close affinity with the orbit of any known asteroid. We found that the meteoroid (or its parent body) most probably entered the near-Earth orbit from the main asteroid belt via either ν 6 secular resonance with Saturn (89%) or 3:1 mean-motion resonance with Jupiter (11%). The long YORP timescale of the meteoroid suggests that it could have been produced in the main astero…

Iron meteorites, also called siderites or ferrous meteorites, are a type of meteorite consisting overwhelmingly of an iron–nickel alloy known as meteoric iron, which usually comprises two mineral phases: kamacite and taenite. Most iron meteorites originate from cores of planetesimals, with the exception of the IIE iron meteorite group. The iron found in iron meteorites was one of the earliest sources of usable iron available to humans, due to the malleability and ductility of the meteoric iron, before the development of smelting that signaled the beginning of the Iron Age.

A meteorite fall, also called an observed fall, is a meteorite collected after its fall from outer space, that was observed by people or automated devices. Any other meteorite is called a "find". As of October 2026, the Meteoritical Bulletin Database listed 1,279 observed falls of approved meteorites, most of which have specimens in modern collections.

Chondrules: First Occurrence in an Iron Meteorite. Complete chondrules and fragments of chondrules have been found within silicate inclusions from the octahedrite iron meteorite Netschaevo. The bulk chemical composition, mineralogy, and mineral chemistry indicate that this chondritic material has properties intermediate between those of the H-group chondrites and those of the enstatite chondrites.

JERSLEV, THE FIRST IRON METEORITE FROM DENMARK. Jerslev is a new iron meteorite of 40 kg, found 1976 on the island of Sjaelland, Denmark. The coordinates are 55°36'N, 11°13'E, and the altitude 20 m. It was excavated from moraine deposits from a depth of about 0.5 m. Jerslev is a coarsest octahedrite of group IIB, related to Mount Joy and Sikhote‐Alin. It shows intergranular corrosion from a long exposure to terrestrial groundwater rich in chlorides.
