Space rock hitting earth 2020
The asteroid named as RK2 was discovered last month and is currently on a trajectory to collide with Earth's orbit and NASA is keeping an eye on it. This asteroid is around 80 metres wide and is travelling at a speed of 6. The US space agency believes that this space rock can be bigger than the size of a Boeing 8 series aeroplane that is almost Meanwhile, the astronomers won't be able to see it from Earth even though the space rock will come close to Earth as the asteroid will zip past at 1. It is reported that once the space rock safely passes planet Earth, it will not visit our orbit again until August However, an asteroid known as SX3 is also heading towards Earth.

Scientists fine-tune odds of asteroid Bennu hitting Earth through 2300 with NASA probe's help
On Asteroid Day, a reminder. The ones to worry about are almost never the ones in the alarmist headlines. Early in January , a "gigantic" asteroid the size of the Empire State Building speeded "towards Earth. At least that's how it was reported by Sputnik, the news site funded by the Russian government. The reality, as the article stated after the scary headline, was that asteroid UO would pass us safely on Jan. That's almost 12 times farther away than the moon.
I scarcely think of the moon as speeding toward my house every night, let alone something 12 times more distant. From the lab to your inbox. Get the latest science stories from CNET every week. But this is the type of language you find regularly in certain outlets that really love scary asteroid stories. The misleading headlines and stories take advantage of the words scientists use to talk about space objects and the connotations some of those same words have in everyday language.
For example, the phrases "near-earth object" NEO and "potentially hazardous asteroid" PHA are astronomical terms used to categorize objects with very specific definitions. If an asteroid comes within 4. This is really just astronomers' way of creating a very big catalog of objects worth keeping an eye on. No other evaluation is done of each asteroid to determine just how "potentially hazardous" it is before giving it that designation.
NEOs fall into an even broader category. To non-scientists, it can seem strange to call an asteroid "near" when it's farther away from us than any human has ever traveled. But of course it makes sense when dealing with the mind-blowing scale of the universe, as astronomers do. Same goes for those PHAs. It makes sense to call them that in the context of the hugeness of space, although most PHAs are not actually potential hazards in our lifetimes.
So next time you see a headline screaming about how a "behemoth space rock threatens Earth," you can check the same sources I do to determine exactly how much you should worry. In fact, I'll take that specific behemoth as an example. In the second half of , many outlets began sounding alarms over the approach of asteroid SF6, which made a close approach by Earth on Nov. It sure sounds like a risky rock heading our way from some of the headlines, so about a week before it was to fly by, I checked the European Space Agency's Risk Page.
The ESA maintains a list of "all objects for which a non-zero impact probability has been detected. When I clicked to get the full risk list and searched the page for both SF6 and its catalog number, , nothing came up. This potential planet-pummeller didn't appear to have made the list of the most threatening space objects.
A search brought SF6 right up. It is indeed a bit of a behemoth, with an estimated diameter of between feet and 2, feet meters and meters. This skyscraper-size space rock could do some real damage on impact. But its close-approach distance was listed as That's just what it sounds like: more than 11 times farther away than the moon, or about 2. Sorry, but this behemoth definitely doesn't threaten Earth. My point, however, isn't that you shouldn't worry about asteroids.
As many dinosaur fossils and the rest of the geologic record tell us, the threat of impact by an object from space is very real. But the main threat comes from the objects that aren't yet in our catalogs. The most significant impact of the past century happened in when a meteor impacted the atmosphere over Russia , creating a shock wave that shattered thousands of windows in the city of Chelyabinsk.
That space rock hadn't been previously observed before it exploded in the sky. The technologies and techniques astronomers use have improved to such a degree that new NEOs are discovered literally every day. This includes some objects actually quite near to Earth, although those tend to be so small they'd probably mostly burn up in the atmosphere if they did impact us, as one did in But we still have blind spots, as the impact demonstrates, so the imperative going forward should be not to freak out over some harmless asteroids, but to devote more resources to continue to scour the sky and complete our catalog so we aren't caught by surprise again.

What Happens If An Asteroid Hits Earth?
Nell Greenfieldboyce. This image of Bennu, taken from a range of 15 miles, shows its unexpectedly rough and rocky surface. A potentially dangerous asteroid called Bennu has a 1 in 1, chance of hitting Earth between now and the year That's according to the most precise calculations of an asteroid's trajectory ever made, and the odds are slightly worse than NASA previously thought. Bennu is a "rubble-pile asteroid" that's shaped like a spinning top, and it's wider than the Empire State Building is tall.
Asteroid warning: NASA says space rock will hit Earth 'again someday'
Representative image of a near-Earth asteroid Photograph: Twitter. Asteroids may be small compared to size of the Earth but they can cause massive destruction owing to their very high speeds. It may be just another day for us here on Earth. We may get up and go about as if nothing is going to happen. But ask those Dinosaurs who were out on the day an asteroid struck Earth. Well, you can't of course because all of them are dead along with around 75 per cent of life at that time on the planet. This is what happens when a huge space rock decides that it is tired of travelling through space and wants to 'settle down' on the cosy planet we call Earth. And this is why NASA and other space agencies around the world keep close watch on any rogue rocks that may be coming our way, or at least make a close call. And one such asteroid has been detected. The asteroid has been named XU6.
Got Plans For Sept. 24, 2182? This Big Asteroid Might, Too
A newly discovered car-sized asteroid just made the closest-known flyby to Earth without hitting our planet. On Sunday Aug. That gives QG the title of closest asteroid flyby ever recorded that didn't end with the space rock's demise. Video: See asteroid QG's orbit around the sun!
Space Rock Alert! Asteroid bigger than Boeing 747 Jet to hit Earth's orbit on October 7
Asteroids from Outer Space! Near Extinction—Level Event Imminent. However, NASA did discover two asteroids on a near-Earth approach last week, and the latest news is another is on the way — soon! The asteroid came within 0. Although this may appear to be a huge distance, at first glance, this is actually relatively close in the infinite scale of space. News on the space-traveling rock says it may be up to feet or sixty meters in size, which is big enough to cause significant damage were it to slam into a city.
The 10 biggest asteroids that pose a threat to Earth in 2020
On Wednesday Sept. By that standard, asteroid NY1 will make a relatively close approach of about , miles 1,, km away from Earth — or just under four times the distance between Earth and the moon. Related: Top 10 ways to destroy Earth. While asteroids like this pose no threat to life on Earth, NASA monitors all NEOs on the off chance that their orbits might change in the future, bringing them closer to a collision with our planet. Studying the characteristics of NEOs can also reveal new information about the early days of the solar system , as most asteroids are rocky fragments originating from that time.

After watching a movie like Armageddon, did you think that such a scenario could really happen? Today, June 30, is celebrated as the International Asteroid Day. The most famous asteroid we know crashed Earth millions of years ago, causing the extinction of dinosaurs. Scientists describe asteroids as "rocky celestial bodies that orbit the Sun and are much smaller than planets".

Asteroid Makes the Closest Earth Flyby a Space Rock Has Ever Survived
An asteroid the size of a car has flown past Earth closer than any seen before without hitting the planet - and NASA admits: "We didn't see it coming. If it had actually been on an impact trajectory, it would likely have become a "fireball" as it broke up in the Earth's atmosphere, the US space agency said. There are hundreds of millions of small asteroids, but they are extremely hard to discover until they get very close to Earth. Lucy mission: NASA launches first probe to asteroid 'swarm' with aim of exploring origins of solar system. Mars Perseverance Rover: Images confirm Jezero crater was ancient lake - and may hold traces of life, say scientists. Mr Chodas told Business Insider: "The asteroid approached undetected from the direction of the sun. We didn't see it coming.
If the possibility of an asteroid called Bennu slamming into Earth a lifetime from now was keeping you up at night, NASA scientists think you can rest a little easier. And with that incredibly detailed view of the asteroid, experts studying potential space rock impacts with Earth have been able to fine-tune their existing models of Bennu's future. As a result, scientists behind new research now say they're confident that the asteroid's total impact probability through is just 1 in 1, While a slightly higher risk than past estimates, it represents a minuscule change in an already minuscule risk, NASA said.
