A week ago, the new Vera C. Rubin Observatory released its first image. It also includes a video of all the asteroids discovered. In just 10 hours, Simonyi’s traditional survey of telescopes and space-time (LSST) cameras captured more than 2,000 previously undiscovered asteroids.
Remind us that despite the lot of space there is still a lot of things happening in our solar system.
Asteroids are the debris left by the formation of rocks and solar system. There are two main areas. First is the asteroid belt between Mars and Jupiter. The second is the Kuiper belt, which exceeds Neptune’s orbit.
But there is more floating there.
The video was released by the team behind Vera C. Rubin Observatory on Monday and showed images of more than 2,000 new asteroids.
Scientists estimate that about 44 tons of meteorite debris face the Earth every day. Yes: Every day.
The good news is that most of them burn in our atmosphere.
But what opportunities are there for larger objects during collision with the Earth?
“In the past, Earth had been hit by large asteroids, and probably something would happen if we waited long enough. But the risk was very, very small.”
“So none of the asteroids we know today have a great chance of hitting Earth in the next 100 years or so. It’s a very healthy time range.”
However, there is no guarantee that what has not been discovered so far is not on the road.
“With our range, of course, we always have the opportunity to discover new asteroids, and they become unpredictable, but it’s hard to predict longer distances in detail,” Weigert added.
The importance of seriousness
There are many groups looking for asteroids to scan the sky, and Weigert said the Vera Rubin Observatory will intensify like a search that has never been seen before.
“The Vera Rubin telescope is really going to revolutionize the way this work is done. I think even people who know what will happen know that it’s on the pipeline, impressed by the way LSST-Rubin and start finding these things,” he said. “So it’s going to be an impressive discovery machine.”
NASA has discovered more than 1.4 billion asteroids and believes that it has identified more than 95% of them in our solar system.
It is estimated that the Rubin Observatory will discover 89,000 near-Earth objects and 3.7 million major belt asteroids.
Now, being hit by an asteroid is indeed an odds.
For ten years, smaller objects, such as asteroids with a diameter of about 10 meters. While not the end of the planets, they can damage windows. The Chilebinsk meteorite that exploded in Russia in 2013 was so big that it did break the window and injured about 1,500 people.

The larger the rock, the less frequency it affects the earth. For example, a 140-meter asteroid affects the Earth about every 1,000 years, while a kilometer asteroid affects the Earth every 700,000 years. The size of an asteroid would be devastating.
The size of the killed dinosaurs is believed to be about 10 to 15 kilometers. These effects are estimated to occur every 100 million years.
Jim Freemantle is the project manager of the Osiris-Rex Laser Altimeter Project at the University of York, Toronto. Osiris-Rex is a sample recovery mission for the asteroid Bennu. There is a small asteroid in his lab.
He believes that tracking and better understanding of asteroids is important in general.
“I’m not lying, what I want to know is that the dinosaur killer asteroids will come to destroy us all. We have other things to worry about,” he said.
“I think it’s prudent to start thinking about where asteroids are or find where asteroids are, because sometimes they’ll sneak into us.”
He also said he was happy to be able to build these observation systems and also planned to try to deflect any asteroid that could collide with the Earth.
He specifically pointed out that NASA’s dual asteroid redirection test (DART) mission is a task for two-plate systems. The purpose is to see if we can see if we can slam something into an asteroid.
The spacecraft crashed into an asteroid to see if doing so can change its orbit. It is considered successful. Now, the European Space Agency has a spacecraft on its way back to the system for more follow-up observations.
Does asteroid affect the moon?
Weigert and his team recently released a preprint study around 2024, a newly discovered asteroid of 60 meters, which has raised some concerns about the chances it will affect Earth in 2032.
But now, we have got the green light to stop worrying about this, as astronomers have somehow perfected the orbit of the asteroid and it turns out that it won’t affect Earth.
However, it still has a 4% chance of hitting the moon.
In a new study by Weigert and colleagues, what it looks like is calculated.
NASA said the chances of asteroid’s direct hit in 2024 may be the size of the football field, constantly shifting. CBC News’ Johanna Wagstaffe and Sarah Galashan discuss what people should pay attention to.
He said that generally, when an asteroid hits a moon or any planet without atmosphere, it makes the crater itself about 10 times the size.
As for 2024, if it hits the moon, the rocks and debris will explode, most of which fall on the moon’s surface. But some of these small rocks can enter the earth, the author said.
“If it is in the right position, it can pass a lot of material to the Earth in the form of essentially small moon rocks, which may be in centimeter size or millimeter size, which is perfect for making meteors, falling stars and will produce a fairly wonderful meteor shower on Earth in a few days and again depend on the moon in a few days and hit exactly where the moon is bright.”
However, this can also pose a threat to satellites.
But Weigert expects that as the orbit is further refined – until the earliest orbit in 2028, which is because it is currently behind the sun – the chances of this happening will drop to zero.
Weigert also explains why it takes time to make better estimates on the asteroid’s path.
“You can see it’s very, very good in the sky, but it’s actually hard to tell how far it is,” he said.
“You can only truly perfect it after watching it for a long time and knowing the laws of physics and how gravity affects the orbit and then say, ‘Well, if it follows the laws of physics and should do that, then travel along this road.’”
When asked if he lost sleep due to the possibility of an asteroid hitting Earth, Weigert simply said: “No.”
“We’ve seen most of the really dangerous asteroids, and we’re continuing to work hard to find more slightly fewer asteroids, but there are still some dangerous asteroids, especially on things like the Rubin Observatory to go online, now that the mission will be done faster than before.”
