Obviously, the quick comment that can be answered here (meaning not kooky), the impact scar is the ~ the size of Earth, NOT the impactor. Somehow there is some confusion about that among the commenters. The impactor was at best 1-2 km across, a faint object to observe from that distance. Not impossible by any means, we have observed outer moons of Jupiter that small, but we have no indication at this point that the impactor went through a period were it was temporarily captured by Jupiter, like SL9.
I think a lot of people in the general public extrapolate the fact that we have found nearly all the earth-orbit crossing asteroids of that size to mean that we have found all the objects in the Solar system of that size. That maybe another source of confusion. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
