Pultusk is an H5 ordinary chondrite meteorite which fell on 30 January 1868 in Poland near the town of Pułtusk.

[1] Made up of rocky debris, it consists of pyroxene or olivine chondrules deployed in massive plagioclase.

The fall occurred on January 30, 1868, at 7:00 pm near the town of Pułtusk, about 60 kilometres (37 mi) northeast of Warsaw.

[2][n 1] The fragments ranged in weight from half a gram to 9.095 kilograms (20.05 lb) (the largest specimen).

Petrologic type 5 xenoliths prevail,[4] so it has been classified as H5: an ordinary chondrite significantly thermally metamorphosed and with the contours of the chondrules frequently difficult to distinguish.
