I have heard that there has never been a meteorite recovered from a

that size probably wouldn't survive entry into the atmosphere.



Which leaves the question of just how large a piece of that weight would be.
As far as impacts on earth, the Tunguska event coincided with the peak
of the Beta Taurid shower, although the connection between the event and
comet Encke which is responsible for that shower is controversial.
