What is the possibility of the earth being hit by a large asteroid?
A week ago, new Vera c. Rubin Observatory Released their first images. It also included a video of all the asteroids discovered. In just 10 hours, the Simoni Survey Telescope with the Legacy Survey of Space and Time (LSST) camera captured more than 2,000 pre -rested asteroids.
It is a reminder that, while there is a lot of space in space, there is still a lot going on in our solar system.
Asteroids are rocks and debris by the formation of our solar system. There are two main areas where most of its part is located. The first is the asteroid belt between Mars and Jupiter. The second is Kuper belt beyond Neptune’s orbit.
But there are still many more floating there.
Vera c. The video released on Monday by the team behind the Rubin Observatory shows images of more than 2,000 new asteroids.
Scientists estimate that roughly 44 tons of meteorite debris falls towards the earth every dayThis is correct: every day.
The good news is that most of it burns in our environment.
But what is the possibility that there is a big object on the curriculum of confrontation with the Earth?
Paul Weigert, a professor at Western University of Physics and Astronomy, Onts, said, “The Earth has been killed with big asteroids in the past, and possibly, if we were waiting for a long time, something would happen. But the risk is very short,” said, “a professor Paul Weigart, a Professor of the Department of Physics and Astrology, Western University, said.
“So we know about any asteroids that today we have an important opportunity to striking the Earth in the next 100 years. So it is a very healthy time horizon.”
However, there is no guarantee that something that has been settled so far is not on its way.
“As we go beyond this, there is always a chance that we can discover new asteroids, of course, and they do not become unexpected, but are difficult to predict in long distances, great detail,” Vigart said.
the importance of Being Earnest
There are many groups scanning the sky in search of asteroids, and Wegart said that Vera c. The Rubin Observatory ramped the search as before.
He said, “Vera Rubin Telescope is actually going to revolutionize such a way of work. I think people who knew what they expected knew was that it was coming under the pipeline, the way LSST-Rubin was really able to dive and start looking for these things,” he said. “So it’s going to be a very impressive search machine that is moving forward.”
NASA has found more and more 1.4 billion asteroidAnd believes that it has identified more 95 percent asteroids one kilometer or big In our solar system.
It is estimated that 89,000 close-earth objects and 3.7 million main-belts will be discovered at the Rubin Observatory.
Now, killing by an asteroid is actually a case of obstacles.
Small objects, such as asteroid, about 10 meters Impress the earth once a decadeWhile the end of the planets, they can break the windows. In 2013, the Chelibinsk meteorite that exploded in Russia was doubled by this size, and actually broke the windows, injuring about 1,500 people.

The larger the rock, the more times they affect the Earth. For example, a 140-meter asteroid affects the Earth about once every 1,000 years and a one that is about one kilometer in size, affects the Earth every 700,000 years. An asteroid that shape will be destructive.
It is believed to be about 10 to 15 kilometers in size to kill dinosaurs. Those effects are estimated to be once every 100 million years.
The gym is a project manager for the Osiris-Rex Laser Ultimeter project at York University at Frimantle Toronto. Osiris-Rex Asteroid was the sample-retrieved mission for Bennu. There is a small piece of asteroid in his laboratory.
He believes that it is important to track and understand better asteroids.
He said, “I don’t wake up thinking, you know, a dinosaur-actor is an asteroid and we are going to destroy all. We have got other things to worry,” he said.
“This is something that I think it is prudent to start thinking, where Esteroids are where or find, because sometimes they secretly secret us.”
He also said that he is excited by these observation systems, and also that there is a plan to try to defraud any asteroid that can occur on the syllabus of confrontation with the Earth.
In particular, he noted NASA Double Asteroid Relations Test (Dart) Mission For a two-sesteroid system. The goal was to see if we could move one asteroid by slamming something into one.
The spacecraft crashed into one of the asteroids, to see if it can change its orbit. It was understood a breakthroughAnd now the European Space Agency has Back to your way in the system For more follow -up comments.
Asteroid to affect the moon?
Weigert and his team recently released a pre-print study about 2024 YR4, a newly discovered asteroid in 60 meters size, at one point this year, raised some concerns about the occasion that it would affect Earth in 2032.
But now we have been given a green light to prevent worrying about this, as astronomers have refined the orbit of asteroid to some extent, and it turns out that it will not affect the Earth.
However, there is still a four percent chance, it will hit the moon.
In a new study of Weigert and Calculation of his colleagues What can it seem,
NASA states that asteroid is likely to direct a direct hit by 2024 YRR4, which may be the size of a football ground, continue shifting. Johana Wagstaff of CBC News and Sara Galashan discussed what people should see.
He said that generally, when an asteroid kills the moon or any planet without an atmosphere, it makes a pit about 10 times its size.
For 2024 YRR4, if it collides with the moon, the rocks and debris will explode with the most falling below the lunar surface. But some of those small rocks can make their way on Earth, the authors said.
“If it hits in the right place, a lot of material can be given on the Earth in the form of small lunar rocks, perhaps centimeter-shape or millimeter-shape, shooting stars perfect, falling stars, and it will create quite amazing meteorous shower on Earth for several days, which depends on again and really and really on the moon.”
However, it will also pose a slight threat to satellites.
But Weigart estimates that as soon as the classroom is further refined – which will not be as soon as possible by 2028, as is currently behind the Sun – the possibility of this will be zero.
Weigert also explained why it takes time to better estimate the path of an asteroid.
“You can see that it is going on very well, very well in the sky, but it really, it is very difficult to mention how far it is,” he said.
“This is only after seeing it in a long period of time and knowing about the rules of physics and how the gravitational class affects the class, that you can actually refine it and say, ‘Well, if it is following the rules of physics, which should do it, that it is traveling with this path.”
Asked if he loses sleep on the possibility of an asteroid that hit the earth, Weigart said quite easily, “No.”
“We have seen most of the really dangerous asteroids, and we are a little less but still continue to work diligently to find somewhat dangerous asteroids, and especially some such as Rubin Observatory are coming here online with some online, now this task is moving forward to complete fast.”
