Asteroid"Skims The Bar".

[DumLum]

Last night an asteroid the size of an aircraft carrier came closer to hitting Earth than the distance between us and the Moon. That's the nearest miss in 200 years!

BBC News - Giant asteroid passes near Earth

Oh crap I've double posted this. I don't know what to do? BAN ME!

No chance of hitting earth? What if it bumps into this BBC News - Russian Mars probe loses its way minutes after launch

According to that BBC article, there's going to be one in 2029 that's not only going to be skimming the bar, its going to be bouncing down onto the very goal-line....

'Earth has several regular visitors like 2005 YU55 - most famously the Apophis asteroid. Apophis has in the past been claimed as a possible future impactor when it returns to our neighbourhood in 2029 and again in 2036. There is, according to the latest calculations, no danger from Apophis either. However, it will pass much closer to Earth on 13 April 2029 - at a distance of 18,300 miles (29,500km).'



Run for the HILLS!!!!

Not much use really is it? We're all going to die on 21st December 2012!

Not again, surely ? that will be three times this year

Narrowly misses the Earth... Scientists have named it Emile Heskey.

What would happen if it hit us? and I don't mean directly because obviously we would die. But say it landed in the English channel what would happen to Brighton?

Obviously we would die.

Obviously we would die.

But how far away from it would you need to be to be safe?

A decent bit of surf off Brighton beach?

Didn't the last one to hit wipe out the dinosaurs? Even the ones that were bigger than us.

But the meteor that killed the dinosaurs was 10km in diameter

 

[Taybha]

Pull the curtains and hide under the table , the dinosaurs obviously didnt have curtains of tables so perished

Let's hope there's no Russian Linesman on duty that day.

OK, how about this then...

HowStuffWorks

Let's say that an asteroid the size of a house crashed on Earth at 30,000 mph. It would have an amount of energy roughly equal to the bomb that fell on Hiroshima -- perhaps 20 kilotons. An asteroid like this would flatten reinforced concrete buildings up to half a mile from ground zero, and flatten wooden structures perhaps a mile and a half from ground zero. It would, in other words, do extensive damage to any city.
If the asteroid is as big as a 20-story building (200 feet on a side), it has an amount of energy equal to the largest nuclear bombs made today -- on the order of 25 to 50 megatons. An asteroid like this would flatten reinforced concrete buildings five miles from ground zero. It would completely destroy most major cities in the United States.
By the time you get up to a mile-wide asteroid, you are working in the 1 million megaton range. This asteroid has the energy that's 10 million times greater than the bomb that fell on Hiroshima. It's able to flatten everything for 100 to 200 miles out from ground zero. In other words, if a mile-wide asteroid were to directly hit New York City, the force of the impact probably would completely flatten every single thing from Washington D.C. to Boston, and would cause extensive damage perhaps 1,000 miles out -- that's as far away as Chicago. The amount of dust and debris thrown up into the atmosphere would block out the sun and cause most living things on the planet to perish. If an asteroid that big were to land in the ocean, it would cause massive tidal waves hundreds of feet high that would completely scrub the coastlines in the vicinity.

I pleased we cleared that up then
