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.

[@jefflindeman]

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.

[@the420autobot]

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.

[@emirkugic]

As a kid, I was always into science and space documentaries and I quickly learned how a meteor killed the dinosaurs and so my childhood biggest fear was born. I was fucking terrified of a meteor killing humans and I remember I couldn't sleep at night because I had severe anxiety.

Stop naming craters and impacts while showing pictures of Meteor Crater. Show the actual sat photos of the places. Meteor Crater is nowhere near as large as Vredefort Crater. Upheval Dome and Manicougan Crater are great pics. Love your channel by the way.

[@NotUsingAnymore03294]

Simple, Just use a teleport portal and a reverse gravity portal on the other side to send the asteroid away Or just use the stop trigger to cancel the move command on the asteroid.

[@SUSsykage]

Or, ya know, toggle the big boi object off...

[@notscot6788]

Just like we'd stop a freight train with a Volkswagen.... One really needs a sense of scale in these matters. It's like asking how many Bic lighters you'd need to warm up the Pacific 10 degrees.

[@Alexehrh]

Isn’t our moon a really old asteroid or something? I know I sound stupid. :(

[@SUSsykage]

I might suggest looking up on the Earth’s formation/creation. I think an asteroid, or a considerably large object, rammed right into the surface of the Earth and then created the Moon from left over debris and gravity pulling everything together...

[@Alexehrh]

PhoeniX & LynX I think that when earth was one piece dinosaurs were around, and the meteor hit where the Gulf of Mexico is, then they all split apart and that’s why the moon was formed, also they have found stuff inside the gulf that is a wierd magnetic substance moving sensitive stuff we don’t know about yet that has a heck of a bunch on energy

Personally, I like the idea of; strapping rockets to similarly sized asteroids, and playing cosmic billiards. Equally as cool is to liquefy or plasmefy the asteroid.

[@ste76539]

There are rather a lot of inaccuracies in this video. For example, "the dinosaurs" are obviously not one species, and they didn't all get wiped out immediately. If they had, we wouldn't have any birds today. Only the 'non avian' dinosaurs went extinct, and it's generally believed today the Chicxulub impact event did not wipe them out immediately, rather they were already on their way out and the asteroid impact was merely one factor of many leading to their extinction. There are more problems here but I've lost interest.
