  • it’s a lesson that if there ever was a big one, we wouldn’t even know or be able to do anything

    This isn’t really correct; near-Earth asteroids big enough to cause global catastrophe are much brighter than smaller asteroids like the one talked about in the article, so they’re much easier to detect. We’ve already mapped the vast majority (over 90%) of >1km asteroids and most of the ones in the >140m range. If any of these were found to have a high probability of hitting Earth, we could send a redirection mission years ahead of time.

    There are also (ground-based) systems like ATLAS which are monitoring the sky 24/7 and would likely provide a few days to weeks of advance warning for small to medium asteroids. That’s too late to redirect the asteroid, but enough time to evacuate an area if necessary.
