The paths of asteroids can be predicted very accurately. There aren't many "anomalies" in space that would affect their orbits. It's the ones that we don't know about that will kill us.
Very true. It is a bit of a concern that ground-based observations are limited to the northern sky, after the southern program
lost its funding way back in 2014, and is yet to be replaced. Of course we do still have space-based detection of the full sky, but the ground-based blind spot is a serious concern. Funding
has now been obtained to fill the blind spot, but until construction is complete that gap is still there...
It's quite revealing of government priorities that the gap existed for a few years with no plans to fill it.
I'm still far more afraid of this asteroid than the Coronavirus, but perhaps that is because I'm not elderly and don't have a compromised immune system so it literally cannot cause me any harm outside of my IRA
The problem with this of course is that you can still be a carrier, and pass it on to any elderly or immunocompromised people you may know.
The coronavirus is more of a threat to individual humans; asteroids are more of a threat to survival of the human species.
