Peter Green Here Is Everything We Know About Dangerous Asteroids As of Now
Every week I get a message from someone asking me to either confirm or deny an article written in a magazine somewhere out there on the internet that claims that an asteroid is about to strike our planet, and we should all be packing our bags and basically going Underground, in other words, I’m going to make this video to kind of clarify the confusion about asteroid, collisions and also so called NGOs or near earth objects that do pass close to our planet, but usually pose no danger whatsoever. So let’s talk about this in a little bit more detail. I know let’s start with this beautiful illustration produced by the European Space Agency. This illustration, categorizes asteroids into five specific types with the more dangerous asteroids on this side and the slightly less dangerous asteroids on the other side, with the part that we’re all curious about being right here. This is the dinosaur, killer, asteroids or essentially asteroids. That are large enough to completely extinguish our civilization almost instantly and possibly even cause another extinction event, in other words asteroids.
That will produce something like this and, as you can see right here, it says almost all of them were found out of roughly about 930 of such asteroids. Like you see the one on the screen here, there are a few kilometers in size, we’ve already discovered 912 and we’re most likely going to find all of them within the next decade. This also means that so we know exactly where they’re going to be for the next hundreds and possibly even thousands of years and as of today, none of them are going to be colliding with anything really they’re going to be staying in space for the next few.
Hundreds of years – and this is actually really important to understand, because in the last two decades or so, we got extremely good at finding new asteroids of all different sizes. The techniques and the actual telescopes used allowed us to discover over a million different rocks or between around the solar system and because of the mathematics of their orbit, and because we understand how their orbits work. We are able to predict where they’re going to be. For the next few hundreds of years – and all of this is actually listed on this site by NASA – and you can always go and check this yourself – this is known as Snell’s or the Center for newer objects. Studies and its main purpose is tracking different asteroids that we’ve discovered and making sure that none of them pose any danger.
This site allows you to go through pretty much the entire catalog of all these so called near earth objects, and here, for example, let’s. Take a look at what’s going to happen in the next year under the distance I’m, going to choose the distance of about five lunar distances, which is about 1.5 million kilometers. So what do we see looks like in the next year, so we’re going to have 10 near earth approaches with the closest one being right here at about 32 of the lunar distances or that’s about a hundred thousand commerce is going to happen on September 1st. So a bad there’s going to be a lot of chatter about this, and a lot of online articles are going to be using this picture and talking about the potential collision yet again, but this side allows you to see everything about the asteroid.
So if you were to click on this right here, this is the asteroid discovery in 2011. You can then actually take a look at its orbit in more detail and even fast forward the orbit just to see where it’s going to end up in the next hundred years or so so here we can actually fast forward this and see if it ever collides With anything and well as you can probably imagine, it’s not going to go anywhere and it’s going to stay in and sorbets for a very long time until at least 2200, which is essentially 180 years from now, and we obviously also know its size, which makes it A relatively small asteroid, so in that sense it doesn’t pose any danger to anything, and neither do any of these other asteroids for the next year or so to make this a little bit more interesting.
We can even look at just the future detection and decrease the distance to about 100 distance, just to see the top 10 asteroids that are going to come close to our planet and the closest one. If what we heard of before the so called Apophis, which is going to pass within about 30000 kilometers over planet in 2029 – and this takes us back to this illustration – so we know that nothing is going to destroy our civilization. But Apophis like asteroids, do have a chance of creating a relatively powerful collision if they do strike a city, for example, as you can see here, we’ve discovered roughly around 80 percent of them and about 20 percent are still missing, but from the ones who have discovered From the we found so far, only Apophis has a chance of approaching our planet within about 30000 kilometers, and we know already that it’s not going to strike our planet.
This has been confirmed by different studies, but the remaining thousand asteroids of similar size that haven’t been discovered yet are very likely just hiding somewhere really really far away and are also most like we’re, not going to come toward our planet or mirror our planet, because anything Near our planet has already been found, so anything that size of Apophis has the same potential devastation effect and also has the potential of coming close to our planet has been already discovered in the last decade, which is really why Apophis is right.
Now the only such asteroid that we’re kind of excited to study a little bit more about, especially because it’s going to approach our planet so closely. But because there is still, I guess, a thousand of these objects. Hiding there’s still a chance that maybe in the next few hundreds of years at least a couple of these do come close to our planet and we do expect a collision with a similar object to occur. At least once every million years or so. And we do have signs of these coaching’s happening in the last few millions of years, such as, for example, the famous Greenland crater. That was discovered a couple of years ago that was essentially created by a rock that’s about similar size to Apophis. So should we worry about these types of rocks? Well, not really, because once again we have discovered all of the ones in the vicinity. We know none of them are going to collide with planet Earth.
We also know that everything that has been discovered yet is most likely just on a completely different orbit and is not going to approach earth at all, and so the only way that’s one of these rocks is going to make it toward earth at some point is Really going to be probably within the next million years, once again, this is not going to be an event, that’s going to happen in the next few hundreds or even thousands of years and that’s pretty much guaranteed, and once again you can check all this yourself right Here on the maoist website, but hypothetically speaking, let’s just say that it did collide with like a big city, for example, in New York.
What would happen this website? You can try yourself. I posted the link for this in the description, but essentially this is what it would look like if the asteroid will strike New York. The orange circle shows you. The size of the crater yellow circle shows you where most of the buildings will be destroyed. Red circle shows you where our debrie will still be quite dangerous, and the green circle shows you moderate damage, although the chance of an asteroid like this here in the city is also pretty low, mostly because most of the collisions today have always occurred over water, because The water represents most of the surface of our planet, but the main point here is that Apophis, like asteroids, do not strike our planet, often enough and there’s going to be no future collisions in the next few thousands of years, but the more dangerous asteroids, the ones That we still don’t really know much about are the so called Tunguska type and the Java beings like meteorites, that have made the news in the last few years.
Here we want to discover about six thousands of such asteroids out of possibly 30000 of them and the smaller they are, the more likely we probably didn’t, find them just yet. The damage caused by a collision of such an asteroid is usually equivalent to a medium sized nuclear bomb, so they are pretty dangerous, but not to the point where they’re going to completely wipe out a civilization and in terms of how often these collisions occur.
It’S anywhere from a few decades, so every few hundreds of years, in other words the famous Tunguska band that are covered in one of the previous videos, is most likely going to happen in the next few hundred years or so, but it’s also probably going to happen Over water once again, where’s the much more common traumatic event is probably going to happen in the next few decades. But once again, as this map from NASA shows, it’s very likely going to occur over water as a matter of fact that each of our beings, like events right here, occurred many times in the past, in other regions and in most of these regions, there was just Nobody there to notice or to witness them, so these events do actually happen quite frequently. So as of right now, these types of events are actually the ones that are most worrisome to the des sciences, simply because we haven’t really discovered that many of these small rocks they’re also very difficult to find, and also because of their randomness in how they can Actually, approach from any angle toward the planet, they also happen frequent enough for us to worry about them, but once again, their damage potential is variable.
Also, most of these end up being bullets, meaning that they explode in the atmosphere and never make it to the surface. Most of these asteroids do not form craters, and the explosion is aerial not on the ground, but at the moment these types of asteroids are the ones NASA and ESA are most concerned about, simply because of their frequency and right now, scientists are trying to focus on Finding more of these and improving our techniques, so we can actually detect them in advance as well.
Current assumptions suggest that there’s, probably over a movie in similar asteroids and all of these asteroids at some point, might actually come close to our planet. Some might even decide to collide with it, but the vast majority, if not most, of these asteroids – will produce no damage to human infrastructure or human life, so they are worrisome but they’re not super dangerous. The biggest worry, of course, being that we are still having trouble. Detecting a lot of these asteroids and for the most part, it’s also very difficult to predict where they’re going to collide and in the last few years only one such collision was actively tracked and predicted by the scientists which I believe occurred somewhere right here in North Africa, but every other collision happened without us, knowing about them. We’Ve only discovered about them, we afterwards and so pretty much most of the modern search is really focusing on these types of asteroids, mostly because we know that there’s going to be more of these coming.
In than a few hundreds of years – and you have a slight chance of causing some damage somewhere and we want to avoid that – where is these larger rocks like app office or even more, are almost certainly not going to happen in our lifetimes. So, for that reason, scientists do not really worry about the larger rocks almost their own. Nevertheless, if you still want to learn more about these collisions for potential collisions with asteroids or just want to know, if something is going to collide with planet Earth, you really should just be going to snails by NASA.
This website has an up to date, database of pretty much every rock discovered, and it also allows you to track all the asteroids and calculates potential chances for collisions as well, but right now, according to the website, nothing is going to collide with Planet Earth for the Next few, hundreds of years so next time you see this picture again and an article claiming that an asteroid might collide with planet Earth, go to snails and check it out by yourself. And so I just summarize all this and also use Tesla rules to here. As an example, just for the size comparison, these asteroids right here – there are quite a lot of them. We haven’t really discovered that many just yet, but most of them produce very, very bright bullets, not a lot of destruction. Nevertheless, we don’t really have good techniques of finding these and they do seem to happen at least once every decade.
So these are the asteroids we’re currently most interested in then we have these slightly larger asteroids and these most likely happen in every few hundreds of years. Possibly even every century, and though we found some of them, we haven’t really discovered that many. These are the ones we’re also kind of interested in, but we don’t expect to have a collision with such an asteroid for at least a few more decades. Nevertheless, a collision with this type of a rock is somewhat scary and most scientists. Today, I want to find better techniques to try to look for these specific asteroids.
Then, as we zoom out, we discover app office. Now these ones are no longer a danger to us. We’Ve discovered pretty much most of them. We also know that a lot of these will not be coming close to our planet anytime soon, and so. Apophis, like rocks, are more of a curiosity and more of a way for us to study asteroids in general, since Apophis is going to be coming close to planet earth in 2029, several missions might be launched here to try to retrieve a sample or the right. Now. Only in Russia has been actually talking about it, so we don’t really know if any of these missions are going to happen, and, lastly, we have these so called dinosaur killer rocks now these ones, we know pretty much most of them there’s, maybe only a couple of Them still missing, but for the most part we know that none of them will be coming close to a planet Earth anytime soon and if a collision does occur with such a rock it’s going to be possibly in the next 100 million years or so so.
Obviously, by then most likely most of us are going to be very, very different. Life will have changed on our planet quite dramatically and hopefully by then humans will also become an interstellar species. So, overall, we don’t really have that much to worry about, but the scientists still want to find better techniques to look for these small rocks simply because well for one.
We don’t want to have a surprise of a sudden boy exploring over a city and also for scientific reasons as well, because it allows us to study the evolution of the solar system as well. But are we going to experience any dangerous collision in 100 years or sold? The very, very unlikely it’s unlikely that there’s going to be anything major happening anytime soon, and the only thing that might happen is a near earth asteroid approach, similar to the one from Apophis. In 2029, and with these four rocks, because their mass is much lower, we also have a lot more options for how to redirect them. If we do discover that one of them is coming toward our planet.
