Bigger Than Burj Khalifa: ‘Potentially Hazardous’ Asteroid to Pass by Earth on Saturday

Sputnik News – August 20, 2021

NASA is keeping a close eye on 1,000 space rocks that are “potentially hazardous” to our planet.

The asteroid known as “2016 AJ193,” classified as “potentially hazardous” by NASA, will whizz past Earth on Saturday, 21 August. The 1.4 km-wide space rock – which is traveling at 94,208 km per hour – will pass within 3,427,445 km of Earth.

The asteroid will approach our planet at 11:10 am ET (8:40 pm IST and 3:10 pm GMT).

NASA will observe the asteroid from 20 to 24 August using radar. It’s 1.5 times the size of the Burj Khalifa, more than three times the size of the Empire State Building, and over 4.5 times the size of the Eiffel Tower – it was spotted in January 2016 by the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) facility, which is part of Hawaii’s Haleakala Observatory.

Every 5.9 years, it orbits the Sun – as it travels towards Earth’s orbit it shoots off in Jupiter’s direction. This visit will be 2016 AJ193’s closest approach to Earth for at least for the next 65 years.

NASA is currently tracking over 26,000 near-Earth asteroids, while over 1,000 are considered potentially hazardous.

Five asteroids pass Earth this week BUT were only discovered 2 weeks ago

Strange Sounds – August 27, 2020

The near-constant bombardment of space rocks buzzing our planet continues, with planetary defenses alerted to a trio of asteroids measuring over 25 meters in diameter en route to Earth’s backyard this week.

To kick things off on Monday, not one but two space rocks over 25 meters (82 feet) in diameter flew past, both of which were detected just this month, leaving little time and space for error in calculating their trajectories. 

Asteroid 2020 PP3, 34 meters wide, passed us by at a distance of 6.1 million kilometers (3.7 million miles), having only been spotted 13 days ago. It was followed shortly afterwards by 2020 PJ6, 26 meters wide, at a distance of 5.3 million kilometers, which was spotted four days later on August 15.

Next up, on Wednesday, asteroid 2020 FF3, measuring 25 meters in diameter came far closer, though maintaining a safe distance of 2.4 million kilometers. This space rock was only spotted on August 14.

Punctuating the mid week are two smaller asteroids, 2016 AH164 (3.9 meters) and 2020 QQ2 (15 meters), which will pass at a distance of six million and 3.2 million kilometers on Wednesday and Thursday respectively.

To put the danger in context, the Chelyabinsk meteor which exploded above Russia in February 2013 was just 18 meters in diameter, proving that it doesn’t take much for a meteorite or asteroid to cause a vast amount of destruction. 

Meanwhile, the recently-discovered asteroid 2020 PG6 is expected to hit the Earth on August 31, 2029, and measures 14 meters in diameter, highlighting once again the need for humanity to remain vigilant lest we be caught off guard and face a catastrophic impact event.

Statue of Liberty-sized ASTEROID barrelling towards Earth as six space rocks set to skim past

RT – May 22, 2020

A huge asteroid that’s roughly the size of the Statue of Liberty is set to fly past Earth on Saturday. The enormous object is among a clutch of six space rocks that will whizz past our planet this weekend.

The largest of the half-dozen space visitors is dubbed 2020 JX and it measures up to 100 meters in diameter, making it around the same size as the icon on Liberty island in New York.

NASA’s Center for Near-Earth Object Studies (CNEOS) is tracking the flying chunk of space material in case it poses any danger to our planet. Thankfully, its calculations forecast that the space boulder will safely pass by at a speed of nearly 18,000 miles per hour at around 19:00 GMT.

The US Space Administration has classified 2020 JX as an Apollo asteroid, the same classification as the meteor that injured hundreds of people when it exploded over the Russian city of Chelyabinsk in 2013.

It has also been designated as a ‘Near Earth Object,’ the term NASA uses to describe “comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth’s neighborhood.”

Asteroid 2020 JX is the largest of four space rocks that will fly near Earth on Saturday. Two additional asteroids will sail past on Sunday and NASA says that all six will pass at a safe distance. The closest visitor will be around 900,000 miles from Earth at its closest point.

Astronomers are currently monitoring nearly 2,000 asteroids, comets and other objects that could be a danger to Earth. However, experts have also warned that undetected asteroids could also pose a threat to our planet.

‘Potentially Hazardous’ Asteroid the Size of Golden Gate Bridge Approaching Earth at 11 km/s

Sputnik News – May 11, 2020

Several space rocks are expected to cross paths with earth this month, but the largest one, and potentially the most dangerous, is the Apollo-class 1997 BQ asteroid, as researchers believe that any space objects measuring close to one kilometre in diameter could have devastating consequences for our planet.

NASA disclosed that 1997 BQ asteroid, also known as 136795, will “closely approach” Earth on the evening of 21 May, sweeping round at a speed of around 11.6 kilometre per second. The space rock was first observed back in January 1997 and is measured at between 0.668 and 1.493 kilometers in diameter, judging by its brightness, which makes it “roughly” comparable in size to the Golden Gate Bridge, the space agency notes.

The asteroid is deemed “potentially hazardous” by NASA, as it belongs to the Apollo category of space rocks, the trajectory of which crosses the orbit of our planet. It might be too early to sound an alarm though, as 1997 BQ will only approach our home from a distance of 0.04115 astronomical units, or 6.156 million kilometres in human terms.

However, NASA’s Centre for Near Earth Object Studies is closely monitoring the object which is considered to be larger than 97% of other space asteroids. Any rocks that are close to one kilometre in size can be potentially dangerous to our planet, the National Near-Earth Object Preparedness Strategy revealed in 2018, as they can create a significant regional impact with secondary effects such as tsunamis, without even making contact with the earth.
