Nasa dart asteroid deflection test

Yeah, but maybe that number is out of thin air?

Maybe it depends on the size of the asteroid, here’s a comparison video which isn’t remotely frightening

And there's this (from a 10/2022 Facebook post of mine):

A heart-stopping simulation has been published showing the first few minutes after the Chixulub asteroid hit the Yucatán peninsula. As well as causing the dinosaurs to become extinct, it triggered a global tsunami that began as a wave more than a mile high. The tsunami scoured the ocean floor thousands of miles from the impact site. Simulation: https://www.youtube.com/embed/aJJOjWX3S1Q (suggest running it at half speed) and news article here: End-Cretaceous asteroid caused massive global tsunami, peaking at a mile high.

But it isn't for Ceres, but a Ceres size asteroid. And the frequency is listed as 4 Billion years.

And how many of them are left in the Solar System other than Ceres? A vanishingly small number I would imagine. If any.

They can spontaneously occur, like how meat makes flies.
