    ~395 earth-moon distances away and 1/20th the size of the object that killed the dinosaurs

      1/20th the size, but 4 time the speed. Assuming the density of the 2 objects were the same, and because energy is proportional to the square of speed, it would cary a similar amount of energy.

    ...but I still have mosquitos hitting my windshield. Hopefully there are not many more objects like that asteroid inbound...

Here's a nicely organized list for you with some history, to let you efficiently worry at scale: https://en.wikipedia.org/wiki/Torino_scale#Objects_with_non-zero_Torino_ratings https://en.wikipedia.org/wiki/Torino_scale#Objects_with_non-...
