How Would We Stop a Large Asteroid?

Last week, an asteroid dubbed "2019 OK" flew past the Earth closer than most asteroids. Had we been less lucky, it would have smashed into the planet with the force of 30* that the bomb that struck Hiroshima... and the scariest part? We didn't even detect it until just days before it flew past. With existing anti-asteroid technology requiring at least a year of warning, it is difficult not to look up at the night sky and be slightly afraid. If another unlikely visitor shows up just days before its collision, could we stop it? In this video, we explore the threats large asteroids pose, and how NASA, among other agencies, are planning to save the Earth from an asteroid collision.

I know this probably isn’t your favourite thing to hear, but your videos are remarkable at being able to help me fall asleep. But they’re not boring in any means, I’m intently listening along. But your voice is really calm and nice to listen to, along with your intonation not being all over the place. Theres not a bunch of interrupts or ads in your videos which I appreciate so much and it’s the perfect length of time. Like, I really really do appreciate what you do. You make fantastic videos that also happen to help me fall asleep due to your consideration for making consistently great content.

The crater you show when you're talking about vredefort crater is Meteor Crater in Arizona.

Afterthought: In addition to the Asteroid "threat", our sun, or even another star many lightyears distant, could fart, and poof, we all fall down. And by "fart" I mean one of the common occurrences of nuclear fusion furnaces (all stars) when they get a little indigestion and burp out a highly directional gamma ray burst. Hell, there could even be one bearing down on us now at the speed of light (approximately 186k miles per second) from some star 50 lightyears away. If our orbit meets it's trajectory, we are all toast. And there's no way to detect it or anticipate it arrival. We would be as good as dead... fifty years ago.

[@maxbootstrap7397]

That crater at 07:15 sure looks like Barringer meteor crater in northern Arizona to me. And based upon clues in the photo, there is no way the crater shown can be over 100 miles in diameter. Based on the claimed age of the Vredefort crater, my guess is, the Vredefort Impact Crater is so worn away by now that signs of the original crater would barely be visible today, even if in a desert area like the Barringer meteor crater.

[@the3dom]

Indeed. That's few miles not 118 ffs! There's a parking on edge of damn thing.

I was also thinking the same thing. I ran the video back and paused it and stared at it, knowing there's no way I'm hell that's over 100 miles long. It looks the be around in the max 2 miles in diameter +-1 just off looking at the roads and landscape around the crater.

For me, this is one of the best channels on KZbin. I love the quality of the content and the way the narration is delivered. One minor criticism: This is the kind of channel where the word “nuclear” comes up often. That’s “nuc-le-ar,” not “nuc-u-lar.” I know its a minor quibble, but it is a blemish on an otherwise stellar presentation.

Ok so hear me out. I feel like people over think this. Instead of one machine to be a end all why not a swarm of space drones with different capabilities? Like a drill drone to decrease the mass of an asteroid and a rocket style drone with cables that could pull and push the asteroid into another direction. I'm not saying this is perfect but I do feel it's better than just shooting a rocket at it with our fingers crossed. Like technology is getting better every year I'm sure itll be more feasible to build alot of small drones than one big machine.

Caused alot of changes and few scientist discovered that the dinosaurs where already dying and having mass migrations before the Asteroid hit, so it was just the final blow. There was Apparently a huge outbreak a Desease spreading throu the planet.
