large asteroid barely misses earth
Quote:
Jan. 28, 2013: Talk about a close shave. On Feb. 15th an asteroid about half the size of a football field will fly past Earth only 17,200 miles above our planet's surface. There's no danger of a collision, but the space rock, designated 2012 DA14, has NASA's attention.

"This is a record-setting close approach," says Don Yeomans of NASA's Near Earth Object Program at JPL. "Since regular sky surveys began in the 1990s, we've never seen an object this big get so close to Earth."

17,200 miles?

Oh well, better stand down Bruce and pals...

How much damage would that even cause? It doesn't sound that big and wouldn't some of it burn up entering Earth's atmosphere or some shit?

From the article

Quote:
The impact of a 50-meter asteroid is not cataclysmic--unless you happen to be underneath it. Yeomans points out that a similar-sized object formed the mile wide Meteor Crater in Arizona when it struck about 50,000 years ago. "That asteroid was made of iron," he says, "which made it an especially potent impactor." Also, in 1908, something about the size of 2012 DA14 exploded in the atmosphere above Siberia, leveling hundreds of square miles of forest. Researchers are still studying the "Tunguska Event" for clues to the impacting object.

Ah okay, I probably should have clicked on the link.

So it's only a bit shit if you happen to be in the area it hits then. Wonder if it'd cause a tsunami if it landed in the sea? Probably not?

Probably would, just have no idea at all how big of one it would create. Some of the tsunami warnings that have gone out in recent years have turned out to be for what ended up being very small waves, causing no damage.

It would be cataclysmic if it landed in London or Manhattan or any other large metropolitan area.

I saw some show on TV and a scientist said if an asteroid hits our planet the devastation would be worst if hits the ocean then he started explained why and my son changed the channel.... fuck.

The Tungaska event was said to be an asteroid and more recent.

EDIT:

It was a meteoroid..not an asteroid.

It will give the Americans yet another excuse to make a catastrophe film, where the catastrophy is only going to his New York. It doesn't matter if it is a massive tidal wave or what have you, it always happens in America and nowhere else. Seems as though Dr Dwayne is safe where he is.

It's a bit cool that it goes within the geosynchronous orbit ring, closer than all the GPS and Sky satelites then.

If you look at the surface of the moon, you can see there are millions of lunar craters which are all caused by objects hitting it. The Earth has had just as many collisions over the years (well obviously it has had multitudes more being a lot bigger) but thanks to our planet being filled with life it hides them quite well.

But not perfectly

Depends on your point of view.

I could live with Glasgow. And even it's inhabitants wouldn't miss Manch... sorry, Liverpool.

(forgot where I was there for a moment)

Well according to some shit shows I watched here in the US, that actually could be the worst thing to do in some cases. Depending on the objects size, what it is made of, etc. Could just split it into a bunch of big objects, that then pelt the earth like a shotgun blast.

<p>We might invade if there is some oil. But yes I think us and the North Koreans would try to team up and nuke it back to whereever it came from. Luckily for Earth, the Chinese, English, French, Indians, Pakistanis, Russians and Israeli's will be there to actually hit the asteroid and save the day.

Yeah but we've got the atmosphere as a bullet-proof vest if it was split into pieces they wouldn't penetrate it.

Not sure even the yanks have a means of targeting something before it enters our atmosphere do they?

Nah we have to send a crack team of oil drillers up into space (after just a few weeks training) where coupled with a crazy Russian astronaut, uptight "real" astronauts, they drill into the core and Bruce Willis saves the day. But that asshole Ben Affleck still doesn't die.

The phrasing of the thread title is chauvinistic. Why not "Earth barely misses large asteroid"?


A super-advanced miniature civilization on the asteroid - as shown on the Simpsons - would be debating blowing up the Earth. We can only pray it never comes to that.

The really big stuff can be predicted many 10's or even hundreds of years ahead. The smaller stuff is very hard to find more than a few days away so then targeting something at that short notice would probably be impossible even assuming the US have the capacity to fire missiles into space. Plus nuking large stuff would need to be a long way from earth if it were to work and as many of these objects may not be solid rock we may just churn them up only for them to reform.

I think that a new space telescope is being worked on that will massively improve detection and prediction. I also read that the most likely way of avoiding collisions will be spraying one side of the object with metallic paint to alter the heating of the object and thus moving it's trajectory and/or using the attraction between a probe and the object to do the same. Both objects require interception a huge distance from Earth.

Asteroid 2012 DA14 will fly so close to Earth’s gravitational pull that scientists say the space rock could experience violent tremors. The asteroid, which is said to be about half the size of a football field, is expected to pass us by on Friday, and possibly even disrupt telecommunications because of its proximity to Earth—it’ll flyby about 17,200 miles from where you and I sit right now, which actually isn’t that far in space talk.

According to Richard Binzel, a professor of planetary science at MIT, this is the first opportunity we’ve had to observe such an event on an object so close to Earth. The phenomenon is referred to as “space weathering,” which typically causes asteroids to “shed a worn-looking outer coating,” Space.com wrote.

“Gravitational forces during the flybys can stretch, rattle and torque these asteroids, causing dark, space-weathered material on the surface to be overturned, revealing the fresh stuff underneath,” Binzel said. “These asteroids experience [seismic activity in the milli- to micro-g range.”

Basically, an asteroid quake is nothing like what you’d experience here on Earth. Still, Binzel says a little shaking goes “a long way” in space. The flyby is expected to occur tomorrow afternoon, so we’ll see what Binzel and his team learn.

The big shame is ya wont be able to see the fuckign thing with the naked eye, and you need a fairly decent telescope to view it aswel.
