Get off your dusty old books dating from before relativity explained Mercury's recession, and just put a bit more faith in actually fact checking reliable sources directly yourself?
Also, please get off your high horse. When you come with such an agressive attitude, the impetus is on you to prove your point, instead of just doing nothing more useful than throwing the cheap blow of an Ad Hominem without any extra substance to it than that.
That 18 km/s figure comes from the Lunar and Planetary Institute.
https://www.psi.edu/epo/ktimpact/ktimpact.html says :
Asteroids hit Earth typically at high speeds of 16 to 32 km/sec
Some move way faster and those are the really most dangerous ones. The 18 km/s is just some average, the reality is of course a spectrum.
That one is said to move "at warp speed" but it is moving at about "only" 6 km/hour. STILL at about twice the size of dimorphos it remains a super dangerous potential extinction event.
Still, the overall logic remains true within an order of magnitude for more or less similarly sized, similar speed asteroids.
Keep on laughing your ass off and judging others while actually contributing absolutely nothing that would be actually useful to the discussion. Congratulations!
