An Asteroid Impact With the Earth in September Is Not Entirely Impossible

It is extremely unlikely, but the probability is actually higher than zero.

Keep September free … because a massive, football field-sized asteroid has a one in 7,300 chance of smashing into the Earth on the morning of September 9, 2019, according to the European Space Agency.

But it most likely won’t hit us.

Known as asteroid 2006 QV89, it has a diameter of 164 feet — that’s double the width of the meteor that exploded in the atmosphere over Chelyabinsk in Russia in 2013. That meteor came from behind the shadow of the sun and wasn’t seen by astronomers until it was already entering our atmosphere.

Current modeling of the asteroid’s orbit shows it more likely passing by Earth at a distance of over 4.2 million miles this September, but ESA says there’s roughly a one hundredth of a 1 percent chance the model is wrong and it hits our planet instead.

Only last month, US scientists took part in an exercise simulating an imminent asteroid impact with the Earth, and NASA administrator Jim Bridenstine warned that we need to take the real-world threat seriously during his keynote speech at the International Academy of Astronautics Planetary Defense Conference in College Park, Maryland.

But it most likely won’t hit us.

Bridenstine also said that detecting, tracking, and studying asteroids and other near-Earth objects (NEOs) should be taken more seriously following the Chelyabinsk event. The resulting shock wave from that 65-foot-wide asteroid damaged thousands of buildings, and debris and flying glass injured over 1,500 people.

Last June, NASA produced a 20-page plan that details the steps the US should take to be better prepared for NEOs that come within 30 million miles of Earth.

Lindley Johnson, the space agency’s planetary defense officer, said that the country “already has significant scientific, technical, and operational capabilities” to help with NEOs, but implementing the new plan would “greatly increase our nation’s readiness and work with international partners to effectively respond should a new potential asteroid impact be detected.”

According to a 2018 report put together by Planetary.org, there are more than 18,000 NEOs.

Hollywood enjoyed a brief spell of asteroid impact-themed disaster movies during the summer of 1998. In the movie Deep Impact, a comet 1½ miles long slammed into the Atlantic ocean off the coast of Cape Hatteras, creating, at first, a tsunami 100 feet high traveling at 1,100 mph (that’s faster than the speed of sound). Then, when it reached shallow water, it slowed but increased in height to 3,500 feet. The wave washed away farmland and cities and eventually reached as far inland as the Ohio and Tennessee valleys (over 600 miles).

But it most likely won’t hit us.

The -tracked asteroid, dubbed Asteroid 2011 HP, is flying towards our planet on a so-called Earth Close Approach trajectory. NASA predicts the imposing space rock will shoot past Earth on the morning of Thursday, May 30. According to NASA’ Jet Propulsion Laboratory (JPL), the asteroid will approach the planet around 11.48am BST or 6.48am Eastern Time. When this happens, NASA said the asteroid will break speeds of around 8.43km per second or 18,857.4mph (30,348kmh).

Asteroid HP is an Apollo-type Near-Earth  (NEA) or Near-Earth Object (NEO).

NASA’s JPL estimates the space rock measures somewhere in the range of 328ft to 754.6ft (100m to 230m) in diameter.

At the upper end of that scale, the asteroid is as tall as the Golden Gate Bridge in San Francisco, US, and the Space Needle in Seattle.

However, even at the lower end of the estimate, the space rock is still almost as tall as Big Ben’s clock tower in London, UK.

The space rock orbits the inner circles of the solar system on a trajectory similar to that of asteroid 1862 Apollo.

The asteroid’s trajectory takes it beyond the orbit of Mars but it does not fly past the Asteroid Belt in-between Mars and the gas giant Jupiter.

All NEOs are comets and asteroids on paths, which orbit the Sun from distances smaller than 1.3 astronomical units or 120.8 million miles (194.5 million km).

One astronomical unit measures approximately 93 million miles (149.6 million km) – the distance from the Earth to the Sun.

Next week, Asteroid HP will significantly cut this distance down to around 0.03149 astronomical units.

This means the asteroid will near-miss the Earth from a distance of just 2.92 million miles (4.7 million km).

In other words, the  rock will approach our home-world 12.26 times as far as the Moon is.

NASA said: “As they orbit the Sun, Near-Earth Objects can occasionally approach close to Earth.

“Note that a ‘close’ passage astronomically can be very far away in human terms: millions or even tens of millions of kilometres.”

After the asteroid ups past the Earth next week, NASA predicts HP will visit us again on May 17, 2027.

Then, the space rock will make many more approaches every few years until September 2, 2184.

NASA asteroid trackers first observed the asteroid on April 13, 2011.

The imposing , dubbed by NASA Asteroid 2019 JB1, is headed towards the Earth on a “Close Approach” trajectory. NASA’s asteroid trackers have calculated a close flyby in the early morning hours of Monday, May 20. According to NASA’s Jet Propulsion Laboratory (JPL) in California, Asteroid JB1 will shoot past our planet around 4.23am BST (3.23am UTC). And when the asteroid nears the Earth, it will reach breakneck speeds of around 26.04km per second or 58,349.8mph.

Asteroid JB1 is an Apollo-type “Near-Earth Object” or NEO asteroid.

NEOs are all asteroids and comets in orbit of the Sun at a distance of 1.3 astronomical units (au).

Just one astronomical unit measures about 93 million miles (149.6 million km), which is the distance between the Earth and the Sun.

’s JPL estimates JB1 measures somewhere in the range of 557.7ft to 1,279.5ft (170m to 390m) across.

An asteroid at the upper end of the estimate is taller than the Eiffel Tower in Paris, France.

The asteroid is also about 200 times longer than a Queen Size bed and 45 London double-decker buses.

If the  rock were to hit the Earth, the force of impact could be cataclysmically deadly.

NASA said: “If a rocky meteoroid larger than 25m but smaller than one kilometre – a little more than 1/2 miles – were to hit Earth, it would likely cause local damage to the impact area.

“We believe anything larger than one to two kilometres – one kilometre is a little more than one-half mile – could have worldwide effects.”

So, is there anything to fear from the asteroid’s flyby next week?

Thankfully, NASA predicts the asteroid will not come close enough to slam into the Earth.

At its closest, Asteroid JB1 will fly past Earth from a distance of 0.04305 astronomical units.

This means Asteroid will come within four million miles (6.4 million km) of our home-world.

In other words, NASA expects the asteroid to fly by 16.76 times as far as the Moon is.

NASA explained: “As they orbit the Sun, Near-Earth Objects can occasionally approach close to Earth.

“Note that a ‘close’ passage astronomically can be very far away in human terms: millions or even tens of millions of kilometres.”

Quick facts about asteroids:

1. Asteroids are the rocky remnants of the early solar system from an approximate 4.6 billion years ago.

2. NASA estimates there are currently 795,070 space rocks orbiting our Sun.

3. The biggest “potentially hazardous” asteroid NASA is aware of is the 3.35-mile-wide (5.4km) Toutatis.

4. NASA has established a Planetary Defense Coordination Office to keep the Earth safe from dangers of asteroid impacts.

5. Most of the asteroids we know of are in the so-called Asteroid Belt between Mars and Jupiter.
