Missed it by THAT much ...
Jul 25th, 2019 at 9:13pm
 
Earth had a near-miss with 'city-killer' asteroid this morning

An asteroid about 100 metres in diameter and racing at 24 kilometres a second has just missed the Earth.


The rock, called Asteroid 2019 OK, sped by our planet at 11.22am on Thursday, passing within about 70,000 kilometres Ė which is a long way away but closer to us than the moonís orbit.

Due to the trajectory of the asteroid Ė flying towards us from the direction of the sun Ė astronomers had no warning it was headed our way.

It is the largest rock to fly at such close quarters to the Earth this year, and possibly for many years.

Astronomers believe the asteroid is between 57 and 130 metres in diameter.

Telescopes only began to pick it up a couple of days ago, with a confirmation it was an asteroid only coming in the past 24 hours.

"Itís impressively close. I donít think itís quite sunk in yet. Itís a pretty big deal," says Associate Professor Michael Brown, from Monash Universityís school of physics and astronomy.

"[If it hit Earth] it makes the bang of a very large nuclear weapon Ė a very large one."

How big?

"It would have hit with over 30 times the energy of the atomic blast at Hiroshima," says Swinburne University astronomer Associate Professor Alan Duffy.

...

"It's a city-killer asteroid. But because it's so small, it's incredibly hard to see until right at the last minute.

"It's threading tightly between the lunar orbit. Definitely too close for comfort."

Asteroids this size tend to pass by once every decade.

Three other asteroids also raced past the Earth on Thursday, but none were as close or as large as 2019 OK. Because it was only just spotted, its existence has not yet been widely reported.

The asteroid was picked up by separate astronomy teams based in Brazil and the US over the past few days.

NASA's Jet Propulsion Laboratory confirmed the discovery. The asteroid passed Earth just 73,000 kilometres away, and was sized between 57 and 130 metres in diameter, according to the lab's data.

"This is one of the closest approaches to Earth by an asteroid that we know of. And itís a pretty large one," says Professor Brown.

By comparison, the rock that killed the dinosaurs was about 16 kilometres across, said Professor Gretchen Benedix, a planetary science researcher at Curtin University.

"Itís not totally out to lunch, these things happen. Itís more rare they happen within a lunar distance," she said.

"If that were to hit the Earth, that would be bad. Something 100 metres across would leave a noticeable hole on the planet."

The Chelyabinsk meteor, which exploded over Russia in 2013, was only about 20 metres in diameter.

Astronomers typically try to pick up asteroids long before they pass by Earth.

But this one was particularly difficult to see because it was coming toward the Earth from the direction of the sun, Professor Brown said.

"It was faint, it was close to the sun. Itís been getting closer to us, getting brighter and brighter, and finally some smaller telescopes have picked it up. Literally, right about now, itís about 70,000 kilometres from Earth," he said.

A person armed with a pair of binoculars and looking at the right spot in the night sky may even have been able to spot it, he said.

Several dozen smaller asteroids in the six-to-12 metre range fly past Earth at a distance closer than the moon every year, according to NASA.

But such a large rock passing so close is unusual.

"These events are rare. But we know, sooner or later, there's going to be one with our name on it," says Professor Duffy.

Australian National University astronomer Dr Brad Tucker said it may be that many rocks of similar size whizz by close to the Earth Ė we just don't detect them.

Canberra during a major sitting?

Now wouldn't that be a hoot?

Or perhaps Mecca,  they would have some serious religious repair work there.

Gaea has already experienced a 'shot' to the chest long ago, which brought about a Mass Extinction.
Now Gaea has created Humanity to 'protect' it from further hits.
The biggest extinction (95%) though was due to Methane rising into the Atmosphere due to Global Warming and Life was 'Polluted' to death.

...sadly, I wonder if Gaea is thinking twice about Humanity being a good idea. Maybe the Monkey/Ape/Human Branch of Evolution was a bad idea? Just look at the Polluted Poisoned World of Humanity and all the Gun's and Defense Armaments are pointed at the Earth.
Looks like Gaea's own creation of Humanity will be its own 'Mass Extinction'.

If Humanity is a mistake that will leave this planet near lifeless, but for Cockroaches, with Pollution, Radiation and shattered Crust - then it only has 1.5 Million years to create another Species to not only PROTECT the Planet, but to spread 'Life' out into other Worlds like a Coral spawning.
Because the Star Gleise will SIDESWIPE our Solar System (pass within the Oort Cloud) resulting in Earth quite possibly spinning way out of its Orbit and into the void due to the Gravitational Impact.

Can Humanity pull it off? Or will it be left to the Cockroaches to save the day?

I think Humanity can.
But not 'directly'.
I don't think other Worlds are for Humanity.
I think its up to us to create a new species (from Orca? Huh) to succeed, where we fail.  Wink

Oh well, did we honestly think we were 'immortal'?

...we only have 1.5 million years. Basically the last 30 secs in relation to the lifespan of life on this planet.

So if a big rock comes from that direction we may have 2 days notice before we are all dead, phew, a near miss from a city destroying rock.

If it hit the centre of the Pacific or the Indian Ocean, there would have been a large splash. A few seconds later following with a thud, as the asteroid hit the seafloor. Assuming that the asteroid lost speed as it entered the atmosphere, it still would have hit the seafloor at a strong speed. The resultant tremors would have lead to tectonic shifts to nearby plate boundaries.

Where are you talking about hypothetically hitting? Between Australia and Hawaii? The biggest result might mean the flash boiling of tonnes of water that will fall as rain over the Solomons, etc. The tsunami will probably cause some concern in the region. But Australia would be well protected.

I would imagine that an asteroid hitting the west coast of India would probably result in India using a nuclear retaliation against Pakistan.

On the Radio yesterday.
Apparently the 'End of the World' is a major anxiety of today's (Media) generation. Pollution, Over-population, World War, etc.
One Presenter expressed a real fear about it, coming from when the USSR/USA Cold War was a real concern - where the proliferation of 'nukes' would have indeed turned this planet into a lifeless wasteland of radiation winds and storms.

Mostly though - the 'End of the World' is a Western trait that also stemmed from those 'Illuminati' fleeing the doom of Europe to the 'New World' (and now they want to flee the USA to Mars† Roll Eyes) and the fact that going by the International Dateline - North America is at the 'End of the World', especially compared to Australia: Down Under - but a 'Day Ahead'† Wink

I think Pollution (like a drug/alcohol overdose) is a real threat and I can see an asteroid hitting the planet one day to give us a wake up call. It might hit hard in the Antarctic - like a kick up the arse! If we're 'lucky'. Wink

Remember: Our Solar System spins around the sun vertical in its travel along the Galactic horizontal plane - so most likely either very north or very south, more than around the Equator for the impact.
