Russian Meteor was chondrite
Which pretty much means it formed in space somehow and has never been part of a larger body (like a star, moon or planet). It is a primitive type of asteroid, formed in the early solar system.
Therefore it has been zooming around for billions of years before exploding in our Earths atmosphere at approximately 33.000 mph last week.
Glad I found some info on alleged fragments found, makes me feel better.
I think I can buy this one, sounds good to me. But you never know…… boom bamboozeld.
