In a rare "time-critical" decision, the James Webb Space Telescope will study the true size of the "potentially hazardous" asteroid 2024 YR4 twice over the next few months. The asteroid has a roughly 2.3% chance of impacting Earth in 2032.

    The way things are going down here I’m cheering for the asteroid tbh.

      Eh calculated impact path ranges from south america through africa and india. None of these are where i want it to land.

        Same here but I figure the rates are going to be really cheap so I can just use up my vacation days and travel to wherever it hits.

      Even if it’s at the top end of the predicted range, an impact would be ~40MT equivalent. Enough to level a city, but not an extinction event by any means; plus the likely impact path is across central America, the Atlantic, central Africa and north India - not really regions that have the resources to respond to a threat like this. Personally I’m hoping it misses, because I don’t see the counties that could do something about it stepping up right now, so you’d be looking at maybe 100 million people displaced from their homes and an insurmountable humanitarian crisis

        In midst of all this funnymaking, I’d like to point out for the record that anybody who genuinely wants it to hit Earth is fucking insane. Some combination of sociopath and psychopath.

          The only scenario in which I would really want it to hit would be if it would lead to moderate global cooling without hitting populated areas. If it can dislodge enough particulates over one of the poles to block out some sun and give us a couple of years of reprieve from global warming, without actually killing anyone or destroying much wildlife, that would be nice.

        Most countries on Earth would treat this as a global catastrophe and put up funds regardless of where it’s projected to impact.

        Maybe not the current US, though.

          Probably not every 4 years. After 2032, Earth will not be near the intersection point of the two orbits for a while. It might be decades before it’s even close.

    For those interested in how they come up with the impact probabilities and why it’s really important that JWST is looking at this, Scott Manley did a great video on this recently: https://youtu.be/Esk1hg2knno?si=Be2u_pxtVPPw6FWt

    An impact from such a rock wouldn’t trigger a mass extinction like the much larger, dino-snuffing Chicxulub impactor did 66 million years ago. But an asteroid that size could wreak regional havoc similar to the Tunguska impactor that flattened some 80 million trees in the Siberian wilderness in 1908

        Unfortunately in a worst case scenario this gets very political, if we do something about it in advance an impactor probe should do the job, if we decide to play the 1/50 odds and lose then the most effective short notice method is a nuke. Not a direct strike but a near detonation which vaporizes a section of the surface of the object with the outgoing plasma effectively functioning as a massive thruster. Actually doing this is not trivial but not hard either (from an engineering standpoint), the tricky part would be actually managing to launch it without every nation on earth that happens to have a beligerant leader saber rattling and stone walling the prospect of a launch until its too late even for a nuke to do any good.

      I don’t believe it is a possible target given how the orbital disk of the asteroid intersects with the surface of the earth. That’s of we don’t change the orbit, if we decide that is necessary, we’ll probably try to get a complete miss instead of just changing the impact site.

      Apophis missed the keyhole, so no chance of impact this century, sorry. It would be a much bigger event, too, about 10-30 times the energy.

      But, this noise does remind me of 2004.
