Asteroids into Meteorites

I was thinking about everything I read yesterday. The only large meteorite that was mostly reported yesterday hit in the Ural mountains in Russia. However, when I read the Wikipedia site about the Meteorite hit it was also reported that another smaller meteorite hit in  Cuba as well. So, I was thinking about this. What may have happened is that if you imagine the larger meteorite having smaller ones in it's gravity field, so when it's little gravity field of itself and other little pieces of a blown up planet or something came towards earth, earth would sort of be like a candle (gravity wise) that drew in all the little moths (asteroids). So, it is possible that many smaller meteorites accompanying the larger one also impacted (through earth's gravity) into our atmosphere. but only the larger ones (Russia and Cuba) made it all the way to the surface of the earth without burning up. Or another scenario is that any other little ones either hit in remote parts of the Earth that were less inhabited. But, possibly we hit the debris field of the larger asteroid and whatever was in the extended gravity debris field was drawn towards earth being a larger source of gravity.
