And Jupiter as well. Without its gravity, we probably would've been wiped out by an asteroid by now.
Our gas giants have protected us from asteroid and comet hits for the most part. The Earth is a very small pin tip of a dot to actually hit, in space terms.
The only thing I do not see in very many places, but have read on the NASA site, I believe, as well as other astronomy pages, is that we are entering a much dustier and "dirty" part of the galaxy now. I think we will be seeing more things come through. I do not think it was an accident that they decided to start really looking for near earth objects flying through. Could be wrong on that, something worth looking more into though. Interesting anyway.
Its only a matter of time and uninhabited real-estate is becoming rarer. As for no one seeing this one coming, well it is a big damn sky, but you also have to wonder whether they would withhold reporting it in hopes of preventing a panic.
That said so long as they don't contain life consuming blobs, giant irradiated spiders or 3 legged martians with friggin lasers on their heads, I'm good.
