We Dodged a Bullet


I'd thought this would be covered but since it wasn't, I'll post that Planet Earth recently narrowly avoided a surprise collision with a "City Killer" sized asteroid. "Narrowly" is of course on a very large but nevertheless a tad frightening scale. The asteroid was only discovered as matter of hours before it swung past Earth, BETWEEN the Earth and Moon. In fact if we divide the distance from the Earth to the Moon into fifths, it was 4/5 of the way to Earth or only 1/5th of the distance to the Moon.

It didn't actually blow up a city but it surely did blow up Twitter and the posts are alternately informative, entertaining, hilarious and disturbing.

Here's one article - https://www.washingtonpost.com/natio...=pocket-newtab

This happens regularly (in human terms) - in geological, let alone cosmic timeframes, just a blip ...

I don't follow social drivel, but didn't something similar also happen about a year ago ?.

IIRC that object, though almost as close, was known months in advance. I don't subscribe to any social media at all. I only viewed these specific logs displayed aloinmg with the Post article. It's the surprise that is notable which was because of it's relatively small size and eccentric orbit. It was relatively small but of a size able to take out a city or cities depending on the proximity due to it's speed, which is also common for asteroids. Yes on one level it is a mere blip, but had it struck say London, New York or Paris or for that matter even the middle of the Pacific Ocean it would've been a rather historic "blip".

The ecosystem doesn't care what the "dominant" life-form is. It survived the obliterations that have already happened, if another occurs life will likely continue.

Will the next "dominant" life-form know or care what preceded it?.

Sometimes the sky literally falls, most of the time it will not. Life will continue. Mass hysteria is only profitable for politicians, religions and businesses (especially media). As syg stated, its nothing unusual. Our planet and the moon are covered with evidence of these collisions other planets even more so.

Hysteria is of no value to me. In fact hysteria is usually detrimental to individuals. In this case hysteria was not an end I am seeking. I'm just wondering, and hoping others might wonder too, if we might just possibly be a bit better off spending a little less of our civilizations budgets on defending and offending each other and just a wee bit more on protecting ourselves against natural disasters. It seems to me if we subscribe to the idea that dinosaurs had pea-sized brains and we OTOH are oh so smart, it may just behoove us to demonstrate that supposed superiority that we might possibly fare a little better.

Seemed to be one of those deals, if it hit.

No one would have been warned in advance.

Something to consider since I have dirt bikes.

Technically, we did the exact opposite of "dodge a bullet" since we didn't try to get out of the way.

What would change if we had been warned?

We are warned since the end of the 1960s about « environmental deterioration, poverty, endemic ill-health, urban blight, criminality » and people keep laughing. And each time a forecast proofs right, its value is denied in retrospect.

An Asteroid that hits ? Oh, the data had not been that reliable after all.

Oh just keep them coming...

Best option is probably for someone to find a way to make Asteroids/Meteors profitable, ie: mining for rare non earth metals. Until that time, I don't think many Governments will care. Money and power sway them.

PS: If the prediction/resolution systems you mention/hope for are as accurate as weather predictions or hurricane predictions then mass hysteria would be prevalent frequently.

Maybe it is because you are likely quite a bit younger than I and don't recall how unreliable weather prediction used to be 40, 50, 60 years ago even within just one day, but I have seen you write this before and I can assure you from experience and you can actually check for example how many times The Farmers Almanac was accurate with what actually took place, but weather prediction has gotten extremely reliable within the range of it's (ever decreasing) limitations.

Since you mentioned hurricanes specifically I'll mention I used to live near Virginia Beach/ Norfolk area and it was very common every Summer for hurricanes to come "waltzing up" the Eastern Coastline. In almost every case, since hurricanes are fueled by thermals, they loosely follow the warm energy of The Gulf Stream. This means that a very high percentage of the time The Outer Banks gets hit pretty hard but since The Gulf Stream veers off to the East, it is fairly rare that hurricanes actually landfall much North of The Outer Banks.

That said when they do it can be catastrophic. There is a large area now appropriately called "Willoughby Spit" that in 1749 and again in 1806, when the Bay rose 15 feet, deposited acres of sand that now has hundreds of residences and roads built on it. There can be little doubt that if that were to occur again possibilities include burial or washing out to sea. So despite the great odds, the consequences can potentially be so high that weather reports often seem overly dire and just wrong. It seems safer to be gladly wrong than unprepared. In this way some extreme weather "predictions" are often mitigated by sheer prudent "what if?".... besides, on Local stations it may feel like Hot Breaking News.

The Federal Weather.com and a few other weather science sites are quite a bit less concerned with sensationalism and are very reliable several days out.

I find it amusing that the NEO program missed this one and it's exactly the sort of thing it's set up to detect.

2010 RF12 has a 5% chance of hitting in 2095 but it's too small to be of concern. No other known asteroids are currently worth worrying about.

Seems like we are of a similar age.
This will always be one of the most accurate weather forecasts: https://britishbeaches.uk/porthallow...nd/photos/7471

With that said, the ancient Chinese did have very accurate forecasts, still are accurate, however, it relies on developing our inner awareness and cultivation along with studying cycles, weather patterns, solar patterns etc... It is quite amusing and fascinating that as mankind continues to look outward for our development and become more reliant on technology, it is still the animals who "know" when its "spring" (or winter) or know (sometimes 7 days in advance) when a tsunami-earthquake etc... will strike. Even squirrels know when winter will be worse then "normal" and they gather extra food, build nests higher up the trees etc... Perhaps, if we listen and observe more we will find that the answers were right in front of us all along.

Proper city planning would never allow mass development on barrier beaches/islands whose main purpose is to act as a flood zone to protect the mainland. Anyone building in those areas should do so at their own risk and their own expense including any repairs/rebuilding. I remember hearing story's from people who were born in the late 1890's early 1900's (they were in their 60's and 70's when I heard the story's), of how the beaches were just for walking, fishing and "bathing", no-one would dare live their except hunting lodges for the weekend etc...

Looks interesting thank you for the link. Is it weather.gov or weather.com?

Did we dodge a bullet, or did the bullet dodge us?
