Earth is Entering a Stream of Debris from Halley’s Comet – Orionid Meteor Shower 2020

FIVE asteroids en route to Earth in just FOUR days

asteroid-alert

Another week, another warning from NASA about an impending barrage of space debris, with no less than five asteroids expected to buzz the Earth’s backyard by Thursday.

To kick things off, 2020 RV2, measuring roughly half the height of the Arc de Triomphe in Paris, or roughly 25 meters in diameter, will pass us by at a safe 5.69 million km.

Next, on October 6, will be 2020 RR2, measuring 26 meters in diameter or… slightly larger than half the famous French landmark, which will sail past at a safe flyby distance of 6.2 million km.

On Wednesday, the largest of the cosmic quintet of space rocks, the 46-meter (half the height of the Statue of Liberty) 2020 RK2 will roar past at 3.8 million km.

The very same day, with a diameter roughly seven times as tall as Shaquille O’Neal (15m) 2019 SB6 will shoot past at 4.5 million km.

Last but not least, the equally half-Arc de Triomphe-sized (25-meter) 2020 SR6 will fly past the Earth at 2.7 million km on October 8.

Unsurprisingly, given the ongoing grim state of affairs besetting the people of planet Earth on all sides, asteroids have now begun to feature heavily in the gallows humor online.

People are pitching movie ideas about asteroids, borrowing heavily from previously successful titles but with an absurd twist befitting this truly bemusing year.

Meanwhile, UFC President Dana White referred to a cursed match between Lightweight Behemoth Khabib Nurmagomedov and pretender to the throne Tony Ferguson, which has failed to materialize half a dozen times at this stage, as potentially triggering an asteroid strike, such is the madness of 2020.

A harmless asteroid is even set to pass Earth just in time for the US election as space rocks continue to find their way into news headlines. Some are relishing the prospect of enjoying one last Christmas dinner before a, by now, seemingly inevitable asteroid strike to finish off this cursed calendar year.

Thankfully, there’s no immediate danger from outer space right now, just a plethora of potential doom down here on Earth.

Two asteroids set to cross Earth’s orbit just hours apart as another Great Pyramid-sized space rock barrels our way #Asteroids #Earth #NASA

asteroid-alert

Two 100-meter-wide asteroids are set to cross Earth’s orbit within hours of each other in the coming days as another space rock, the size of ancient Egypt’s Great Pyramid of Giza, careens towards our planet.

NASA’s Center for Near Earth Object Studies, which tracks asteroids and comets that will come close to Earth, has confirmed that it is monitoring two asteroids that are due to hurtle past on Friday, September 25. Both bodies are classed as Apollo asteroids, meaning they will cross Earth’s orbit as they fly through space.

The first asteroid, which is named 2020 RO, is estimated to be up to 130 meters wide. It will fly past on September 25 at 00:10 EST at a speed of 11.84km per second.

The second asteroid, named 2020 SM, is expected to sail past Earth later that day, at a speed of 18.43 km per second. The slightly smaller space rock is estimated to measure up to 100 meters in diameter.

Although both asteroids are classed as near-Earth objects (NEOs) they are forecast to sail safely past our planet, despite coming into contact with its orbit. They were both discovered this year.

On September 29, a giant 200-meter-wide asteroid will silently pass Earth at a distance of around 1.78 million miles. The enormous visitor is comparable in size to Ancient Egypt’s Great Pyramid of Giza.

The interesting spate of asteroidal activity comes hot on the heels of an amateur astronomer in Brazil discovering a large asteroid that somehow slipped past Earth’s main planetary defenses just last month.

The discovery served as a reminder to the world’s space agencies that there are still many asteroids out there that have yet to be detected.

Three HUGE asteroids headed towards Earth, after amateur astronomer spots massive space rock our planetary defenses MISSED #Asteroids #Earth #NASA

asteroid-alert

Scientists are getting better at spotting inbound, “potentially hazardous” asteroids, with three more measuring over 15 meters in diameter on the way this week. However, asteroid hunters missed a 1,000m space rock just last month.

The Earth is under near-constant threat from space debris in the form of asteroids and meteorites, and this week is no exception, with two smaller space rocks due to buzz the planet today and tomorrow.

Meanwhile, later in the week, NASA gave the ‘heads up’ about three asteroids, each measuring over 15 meters.

On September 16, asteroid 2020 RW3, which measures roughly 18m in diameter (or twice as long as a London bus) will shoot past the Earth at a distance of 2.5 million km.

The week’s asteroidal assault will conclude on Thursday with two much larger space rocks: the 30-meter 2020RN1 (twice the height of the Hollywood sign) and the 62-meter 2014 QJ33 (30 Shaquille O’Neals stacked on top of each other), which will pass at a safe distance of seven million and 2.5 million km respectively.

Lest anyone get too comfortable though, in yet another reminder that humanity must remain ever-vigilant for spaceborne threats, an amateur astronomer in Brazil discovered a large asteroid that somehow slipped past Earth’s main planetary defenses just last month.

Asteroid 2020 QU6, measuring 1,000 meters wide, large enough to inflict significant damage here on Earth if it hit, was spotted by amateur astronomer Leonardo Amaral based at the Campo dos Amarais observatory in Brazil, on August 27.

Mercifully it passed us at a distance of 40 million kilometers, over 100 times the distance between Earth and the moon, on September 10.

Amaral managed to spot the asteroid thanks to his somewhat unique vantage point as he is based in the southern hemisphere, whereas many of our asteroid-hunter telescopes are based in the northern hemisphere.

“This discovery reminds us that even though we’ve found most large NEOs [Near-Earth Objects] we haven’t found all of them,” said Casey Dreier, chief advocate and senior space policy adviser for The Planetary Society.

Asteroid double the size of Pyramid Giza to enter Earth’s orbit on 6th September 2020 #Asteroid #Earth #Apollo #NASA

asteroid-alert

The massive asteroid has been classified as an Apollo asteroid because it crosses Earth’s orbit. It was first spotted by astronomers a decade ago and called 465824 (2010 FR).

National Aeronautics and Space Administration (NASA) has been tracking an asteroid which is twice as big as the iconic Egyptian monument, Pyramid of Giza. The gigantic celestial object is expected to collide with Earth’s orbit at around 15:30 IST on September 6. As per the reports, the asteroid is up to 270 metre wide and 886 feet tall.

The massive asteroid has been classified as an Apollo asteroid because it crosses Earth’s orbit. It was first spotted by astronomers a decade ago and called 465824 (2010 FR).

However, scientists at the Center for Near-Earth Object Studies (CNEOS) confirmed that like many asteroids that have been spotted to fly by our planet of late, it won’t be a threat.

According to NASA, a NEO is a term used 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 neighbourhood”.

The asteroid in question is a NEO as well as it is within 1.3 astronomical units from the Sun (1au = 14,95,97,871 kilometres).

Even though asteroids like these are harmless because of their distance from Earth, they can come closer than expected due to the gravitational pull of other planets which can result in a change in the trajectory of their orbit. Not only this, but the Yarkovsky effect can also nudge an asteroid orbit. The change in orbit takes place when an asteroid absorbs sunlight and then re-emits that energy as heat or radiation.

“Occasionally, asteroids’ orbital paths are influenced by the gravitational tug of planets, which cause their paths to alter. Scientists believe stray asteroids or fragments from earlier collisions have slammed into Earth in the past, playing a major role in the evolution of our planet,” NASA said.

Also, On September 1, asteroid 2011 ES4 will be closer to our planet than the Moon. The estimated distance of the asteroid from Earth is 1.2 lakh km. Another asteroid named 2020 QG5 is approaching Earth again after 16 years on the same day. Both these asteroids won’t be a threat to our planet as well because of the distance and its small size which will be destroyed upon entering Earth’s atmosphere.
