    Scott Manley did a great video explaining how easily we could redirect it if we found out it was going to hit the earth. We have multiple launch vehicles that can launch a mass at sufficient velocity to nudge it the small amount we need.

    Fly safe.

    In the world of astronomy a billion kilometers is like a missile hitting the neighborhood next to yours. So while there’s a good amount of hyperbole there, it’s still relatively close. You’re still shaken up by it hitting your town. And eventually we will win the lottery and have an astronomical event outside our control devestate the earth. It’s happened before.

      Well, a billion kilometers is almost 7 times the mean distance between the earth and the sun. Asteroids pass in that distance all the time. We’re currently closer to Ceres (the dwarf planet) than that and its on the other side of the sun from us.

    Well when they’re saying there’s 2% odds, that’s…probably still higher than you want for the probability of a world ending asteroid strike.

      It’s not a world ending strike. It’s 2.3% odds that a city ending strike lands somewhere on earth, most likely in the ocean.

      It’s a fraction of a fraction of a % that it’ll hit somewhere with any humans at all, much less a populated city.

      And on top of that, we have until 2032 to decide what to do about it, with enough time to potentially redirect it with technology we’ve already demonstrated that works. And if that isn’t enough, we just need one or two more data points to figure out almost exactly where it will hit, and can evacuate the area.

      Just like we do for hurricanes and other natural disasters.

      This is not an emergency, this is an easy mode try out for a real disaster.

        So it’s going to be horribly fumbled in the stupidest manner possible and will definitely become a worldwide disaster. Got it.

          The caveat to THAT is that we do have historical data, and if we can find one or more images confirmed to be the target, we could narrow it down without additional imaging.

        The only thing to ever have a higher score than this one on the Torino scale (before further calculations reclassified it as a 0) is scheduled to come close by in 2029. Should be interesting to watch, at least.

        City ending will cause weather chaos and possibly radioactive fallout.

        But the funny part is that you think 2032 is enough time. Humans are USELESS when we need to do large international projects to a deadline.

      There’s a great video by Scott Manly on the subject if you want to learn more. It’d smaller than some nukes we’ve tested, and would land somewhere around the equator between the Atlantic and China if it does hit. It looks surprisingly feasible to deflect, but it’d be a time crunch to put a mission together in only a couple of months. Plus it might deflect it into hitting a different country.

    It’s pretty much speculation based on a probability that includes the chance to hit a narrow ring of places along earth’s surface, but we don’t know how dense it is, although we’re relatively sure it’s solid, and whether other debris will change its path before it remerges in 2028. It has no risk factor to us until 2032, just in case people are wondering why reputatable science journalists aren’t completely poopooing the narratives of other outlets. We’ll know what it eats for breakfast by 2029.
