I watched the first one of these, the second one showed up on another search, it's about a minute shorter.
What If The Largest Asteroid Hit Earth?
What If The Largest Asteroid Hit Earth?

An asteroid named 2020 OY4, made its closest approach to our planet on July 28, when it was discovered just 26,000 miles away from Earth. It flew by earth at the range that rivals the orbits of some high-flying satellites.
This is extremely close in astronomical terms, and just 11 percent of the average distance between the Earth and the moon.
In fact, the data from NASA that tracks near-Earth objects suggests that the close approach of this asteroid was the closest that any asteroid will come to our planet for the next year.
However, if you measure by the minimum possible close-approach distance, one small asteroid, may come even closer in November, potentially passing at an incredibly close distance of just over 4,700 miles.
Astronomers snapped a photo of this asteroid on July 27 when it was located around 155,000 miles from earth.
Using one of the remotely-operated telescopes known as "Elena," Astronomers took a single, long exposure shot, in which the asteroid can be seen in the middle as a tiny, bright white dot.
The numerous white streaks in the image are stars, which appear like trails because the telescope was tracking the asteroid as it moved at high speeds of 27,700 miles per hour relative to Earth.
The asteroid, which measures under 10 feet, was discovered on July 26, 2020 during an astronomical survey conducted by the Mount Lemmon Observatory.
Despite it's close approach, there was no chance that the asteroid would end up colliding with Earth.
And even if it hits earth, Asteroid of this size always burn up in the atmosphere, meaning they pose little risk.

Depends on the size of the comet of course, but anything a mile or more in diameter would extinguish civilization and most (over 99 percent) of humanity. The EMP would take care of most or all of the comm networks worldwide.
The only shelter would be underground, and it would have to involve prepper type stockpiling of supplies, as the surface temperature would rise unbearably, then drop unbearably.
They do point out increased precipitation (that would assume impact on water, which is 7:3 vs a land impact) but much of that would be freezing rain, snow, and ice, leaving a circular "ice age" glacial area on part of the Earth. After the cloud cover blocked all sunlight, a condition that would last for months or years, the falling temps would cause a halt to the hydrologic cycle, meaning, no rain anywhere. The early rise in atmospheric temps might melt off all high-altitude snow and ice, and until the remaining fresh waters in streams and rivers froze as the temps crashed, everything else would low out into the salty oceans.
We missed a chance to whack this asteroid in a test of our anti-satellite/bombs from orbit.
Who the hell was in charge of this fiasco?
A successful destruction of an small asteroid would send chills down the legs of the Russians, Red Chinese, No. Koreans and Iranians because it would show that we can take down their satellites, rockets, etc. if they attacked.
Come on NORAD, etc. Get with the program and blow up something. “In space, nobody cares”.
It's unclear that a comet strike would generate an EMP.
In the book, they estimate the impact of the hot fudge sundae would be equivalent to 647,000 megatons. "About three thousand Krakatoas" and "would vaporize about sixty million cubic kilometers of water" for a water strike. But the Hammer is ten times larger.
Why?
Was it too good for our satellites?
Gasp!
Is it... racist!!!! against our mechanical space brothers?
It's not unclear at all. It would. Early in the 20th century, a midair detonation over Lake Michigan knocked out at least six municipal power generators of the time, sent a surge up the Grand River channel in Grand Haven, lit the surrounding surface of the Earth for miles, and was so evident people ran out of their homes into the night, sure that the world was ending, as far inland as Battle Creek. This was a small, transient event that left no other traces.
It really just needed to go to the bathroom, and our satellites lack those facilities.
Obvious bogus excuse is bogus.
No one uses the facilities anymore.
"The urine sample was Bill's, but the handwriting was Monica's."
Well now.
That pretty much proves that someone in the feds leaked that the Standard Hotel was under observation.
Should always be the first line of any article about Near Earth Asteroids, fly-bys, and the like.

It's been agas, but I seem to recall there was some sort of communication going on between the USSR and US, when they collaboratively snuffed out the Chicoms.
Aren't we still talking about a sci-fi novel? They weren't writing non-fiction.
I have read alot of Larry Niven. I liked Asimov too. Couldn,t get into Jerry,s stuff much.
I don't know his work, and due to his gratuitous bashing of things in his "Chaos Manor" monthly column (hmm, that was in one of the computer magazines, remember those? ;^) including one really dumb one regarding modem data formats (remember those? ;^) for his communication with his then-publisher, I wasn't inclined to read a book's worth of him until Lucifer's Hammer. Probably worth reading his collabs with Niven, but I just don't read fiction. :^)
