478 miles per second...Is that about average for a space rock?

I did not realize mercury had such an eccentric orbit. So, how far into the future can we predict 6 body gravitational problems?

If you're looking for
one more thing to worry about, consider how feasible it is now, and increasingly will become more so, for an advanced nation to send out a robotic spacecraft to rendezvous with one of these Earth-skimming bodies and deliberately steer it to coordinates on Earth.
It's matter of hitting a spinning ball at a particular spot with a projectile, but this kind of problem is what computers are for.
For any given combination of mass, density and relative speed, it's possible to calculate blast and thermal effects with reasonable reliability.

If at first you don’t succeed, try again.
These rocks are getting closer and closer.

“...28,655 miles per hour...”
Hell, my ‘73 TR6 went faster than that. (Heh).
