Bruce Willis Call Your Office: Largest Asteroid in a Century to Scrape By Us

Asteroid Florence, one of millions of pieces of rocky, primordial space debris that have been zipping around our solar system for a few billion years, is going to pass really, really close to Earth tomorrow. Where's Harry Stamper and his merry band of oil drillers when you need them?

And by "really, really close" I mean about 4 million miles. Which seems like a lot of distance if you and the family have just piled into the Griswold Family Truckster for a trip to Wally World -- if Walley World were on another continent and there was a land bridge to Siberia still in existence, that is -- but it's actually just around the corner, in terms of space distances.

Our planet travels through space at about 8 miles every second. That's fast. That also means we easily cover 4 million miles in less than a week. So if we'd been off in any meaningful way as to the three-mile-wide Florence's trajectory or path it could have been Lucifer's Hammer (though that was a comet that had broken apart or calved, which this asteroid wouldn't necessarily do) all over again and we can just go ahead and cancel the Neil Diamond Holiday Special on ABC right now. Consider that the dinosaur-killing asteroid that darkened Earth for years from the ejecta it sent up into the atmosphere (changing planetary albedo greatly) was only about six-miles across. Florence would sting us just a little bit, in other words.

At any rate, all the NASA science boffins have been tracking Florence for a couple of days now, mostly using ground-based radar, and they say that this is the closest the asteroid has come to us since 1890 and that it won't approach as closely again until about the year 2500. When either a Kennedy, a Bush, a Clinton, a Trump or an Obama will no doubt be running again. ;-)

By the way, we really only learned about Florence's existence in 1981. Ever wonder how many other near-Earth objects there are out there, passing agonizingly near to us?

Google search on large asteroids passing close brought up this article:

http://www.telegraph.co.uk/...ose-earth-wednesday/

It is talking about an asteroid 1/4 - 3/4 a mile in diameter. We didn't discover it until 2014. So yeah, we are all just living on borrowed time.

Says, "An asteroid the size of the Gibraltar rock has beee the largest asteroid to come this close to Earth since 2004.
On Wednesday afternoon, the object passed close to our planet, zooming by at a distance of just over a million miles (1.8 million km), but with no chance of impact, according to Nasa scientists."

"An asteroid a mile wide hitting the Earth would unleash as much energy as around 1,000 atom bombs like the one dropped on Hiroshima in 1945.
The blast would completely destroy a city the size of London or New York and cause extensive damage for hundreds of miles."

and, "In 2004, the 3.1-mile (5 km) wide asteroid Toutatis passed about four lunar distances, or just under a million miles (1.6 million km) from Earth."

I'm beginning to think that we are much more fucked than I thought.

And it's at times like this -- when I read that stuff you posted -- that I realize your signature/tagline is massively apropos. ;-)

I wouldn't worry about an asteroid taking out the planet anytime soon. The ones that can do that have pretty much all been found (we are at about 95%) and they aren't going to hit anytime soon. There is always a chance they get bumped and change course, but highly unlikely. And there is also the chance one of the few we haven't found will impact, but again highly unlikely.

However, there are still plenty of them out there that we haven't found that are big enough to take out a city. Odds are still pretty low that they will a) hit Earth and b) hit a highly populated area, but it can happen. A bullseye on a major city could be the greatest natural disaster known to man.

Yeah, even the Lucifer's Hammer writers (Niven and Pournelle) had to imagine a very large, undiscovered planet in the outermost areas of the solar system, something that moved -- very, very slightly -- the comet out of its regular orbit, causing it to fall down into the inner planets, where Earth resided.

Fortunately, the giant planets do a good job of sweeping up any off-kilter or wandering celestial bodies that might have a mind to head our way. :-)

Unless, of course, we piss of the bugs that live on Klendathu. Would you like to know more?

Ha! One of the greatest movies of all time!
