  This seems like it's off by ~6 orders of magnitude (see https://en.wikipedia.org/wiki/Impact_event https://en.wikipedia.org/wiki/Impact_event)

    Amusing addendum, in order for this asteroid to have a 5Kt impact energy it would need to be traveling at around 50 mph as it impacts earth. A typical impact velocity would be something closer to 30,000 mph.

  I would recommend using a calculator designed by experts, like https://impact.ese.ic.ac.uk/ImpactEarth/ImpactEffectsMap/ https://impact.ese.ic.ac.uk/ImpactEarth/ImpactEffectsMap/ instead of ChatGPT. I get a low-end estimate of tens of megatons.

  ChatGPT also believes the moon is made out of green cheese. (Less snarky: It hallucinates an answer. It can't do math. Do not rely on ChatGPT for math. Or facts.)

  Based on even the slightest bit of checking you could see that that number is utter bullshit, 5Kt is nothing at all like the impact of an asteroid of this size. https://en.wikipedia.org/wiki/Chelyabinsk_meteor https://en.wikipedia.org/wiki/Chelyabinsk_meteor Was 100 times as much and was only an 18 meter asteroid.

At 400m diameter we should expect an impact energy of ~3Gt, which would be one of the most energetic events in human history, if not the most. For a comparison, the Lake Toba eruption (which is suspected of causing homo sapiens to almost go extinct 76kya) is estimated to have been in the 1-2Gt range.

  Only 400m in diameter.

    ... The Chelyabinsk meteor had ~20m of diameter. The impact energy of a 400m diameter asteroid is somewhere in the same ballpark as the deployed nuclear arsenal of the United States. Not extinction-level impact, but wherever it hit would definitely feel it.

      Yes some place will feel it somehow, 70% chance it strikes an ocean and creates a tsunami. But the world will go on, people will shrug their shoulders and go on with life. If it was a 60 mile wide asteroid, now that would truly be the end.

        This would wipe out an area equivalent to a mid sized country and would possibly have global effects. The threshold for that is somewhere between 250 meters and a kilometer but we fortunately do not have any data to make that much more precise. You definitely wouldn't shrug your shoulders and get on with life, it would be the most important event in your life assuming it didn't end. Depending on where it happened the economic impact of such an incident would destabilize the world economy for decades.

400m diameter is certainly pretty bad if hit. And why is there no articles about it on Wikipedia yet?
