description Pultusk Overview
Pultusk is an H5 ordinary chondrite meteorite that fell near Pułtusk, Poland, in 1868. The event produced an unusually extensive shower of stones over a broad area, and thousands of individual fragments were subsequently recovered. As an H-group chondrite, it contains abundant iron-bearing material, while the petrologic type 5 classification indicates that its original chondritic components were substantially altered by heat within its parent body.
help Pultusk FAQ
Why are Pułtusk meteorite pieces sometimes called peas?
The 1868 fall scattered a huge number of small stones, many of them only pebble-sized, across the countryside near Pułtusk. Collectors consequently use the nickname "Pułtusk peas" for the smallest rounded individuals.
What does the H5 classification of Pułtusk mean?
The H identifies an ordinary chondrite group with relatively high total iron, while 5 indicates substantial thermal metamorphism on its parent asteroid. Its original chondrules remain recognizable even though heating altered the rock internally.
Was the Pułtusk meteorite a single stone?
No, it broke apart in the atmosphere and produced one of the best-known meteorite showers of stones. Thousands of fragments fell over a broad strewn field in Poland.
How can collectors recognize a genuine Pułtusk meteorite?
Typical pieces may show a dark fusion crust, a gray chondritic interior, metal grains, and rounded chondrules. Appearance alone is not sufficient for authentication, so provenance and expert classification are especially important for small specimens.
