On February 15, 2013, a very bright meteor shone in the early morning hours over Chelyabinsk, Russia, and subsequently exploded above the Earth's surface. The resulting pressure wave blew out thousands of windows in buildings within a radius of several kilometres.
Pieces ranging in mass from a few grams to 570 kg were found, the main piece that fell into nearby Lake Chebarkul. It was pulled out in October 2013.
It is a stone meteorite - chondrite, type LL5.
You can find pieces weighing from tens of milligrams to several grams.
