And if you recall, that particular object was closely followed/in tandem with another noted asteroid that came basically along the same path.
So my point is ANYTHING in space can have trailing/leading objects that we don’t know about. At least until we are hit!
True, but I don’t think they ever got an accurate count on the number of fragments produced by the Chelyebinsk asteroid. It exploded something like 20 miles above the earth’s surface when it entered the atmosphere. The estimated size was about six times the current asteroid passing close to the earth and it was nearly impossible to sort out which impact fragments originated from trailing objects and which from the asteroid itself.
