That was just the G-Fragment. Comet Shoemaker-Levy 9 broke up into 23 fragments, A through W in its near approach to Jupiter in 1992. The G-Fragment was estimated to be 2km in diameter. They crashed into Jupiter at 60km per second over a six-day period in 1994. https://en.wikipedia.org/wiki/Comet_Shoemaker%E2%80%93Levy_9

It’s pretty astounding that this has happened in our lifetimes, given the scale of galactic time. What I find interesting is that when we observe comets and asteroids, they always seem to be travelling at relatively low speeds. What happens if we encounter some solid mass that has been ejected from a cataclysmic galactic event with a huge amount of energy and it enters the solar system at something like 1/2C. We probably wouldn’t even see it before it’s too late.

If the challanger disaster wouldn't have happened the Galileo probe, which made these pictures would have already been in orbit around Jupiter by the time of impact.
