2. An asteroid with the mass of a "city-sized asteroid" would move the Earth by a few feet?

I find that surprising considering the mass of the Earth compared to a city-sized asteroid. Is this accurate? If it is, how close would it have to come to the Earth's surface to have that effect? Gravitational force is inversely proportional to the square of the distance.

A version of the paper is available on arXiv. Jim__ Sep 2024 #4

So is the suggestion that it would move the earth "a few feet" a guess, an exaggeration, or based on the math? Martin68 Sep 2024 #5

They're not looking at single encounters, but rather at simulations of cumulative effects over years. Jim__ Sep 2024 #6

The quote I was referring to was clearly referring to the effect of only one black hole, and it specifically refers to Martin68 Sep 2024 #7
