Another very large asteroid on its way

[80DGY]

Where's RagingRiceBoi's dad when you need him?

Tell him an asteroid is trying to pinch his BMW, next thing you know, the pants will be down, old feller armed and he'll piss all over the damn asteroid.

That'll **** it

:D

:rotflol:

i think you should pm him so he can ask his old man to save all teh bmw's in teh world...although he has a special bmw garage - which i'm sure is invincible to asteroids and acts of god as well as theives.

it may be off topic, but i'd just like to say that Spiny Norman rocks.......

Go hard Bill.

The earth's surface is approx. 70% ocean, so it makes sense that a meteor would most likely hit the ocean. Most of the oceans are about 2-3 km deep, so a 1km asteroid would create a massive tidal wave. A 1 km sized asteroid is probably at the cusp of what could do terrific damage. Models of collisions with objects 2-3 km upwards suggest that there would be significant ejecta, that would block out sunlight, irresepective of where it landed. Also, don't discount the effects of a portion of the ocean being boiled away.

this is bloody funny

[Turbo4WD]

What would happen if a 1km asteriod hit the pacific ocean where the marinas trench is (11km deep) - would it hit the bottom and how high would the tidal wave be?

Also what would happen if a smaller one - say .5km hit in the same spot?

[Damlowet]

Ocean or no ocean, something that massive traveling at over 30km per second aint stopping for a thin layer of water.

Try and imagine a basketball sized rock weighing 500kg moving at 50kmh passing through about 3.5mtrs of water! No problem.

The telling part would be how dense the actual rock is. If it is quite porus, the thing will probably cause an explosion of immessurable size, destroying anything within quite a large radius.

Think Tunguska

"The explosion over the basin of the Podkamennaya Tunguska River, Russia, on 30th June 1908 was equivalent to 10-15megatons of high-explosive and resulted in the devestation of a total area of 3,900 km2. The shock wave was felt up to 1000km away. The cause is thought to be the energy released when a stony meteoroid 30m (THIRTY METRES!) in diameter travelling at hypersonic velocity at an incoming angle of 45o totaly disintergrated at an altitude of 10km." Thanks G.B.R 1998


If the thing strikes the ground/ocean, look out! It would probably cause a dust cloud big enough to block out the sun for a couple of years.
Not to mention that it would probably trigger thousands of earthquakes around the world which wouldn't have normaly occured for hundreds of years to come.

So now is the time to move away from that fault line that you built your house on. No wonder the land was sooooo cheap!

Whoop's

The wave would probably be 10-20kms high traveling at the speed of sound.

It would most definately hit the bottom its going bloody fast 11km is SFA at asteriod speeds. I have no idea how big the wave would be. I say it would eaisly bigger than 1km high, which sounds scary. A .5km wide asteriod would do way less than half the damage as a 1km asteriod if that is what you are after.

I suspect that most of the volume of water would vaporise well prior to reaching the speed of sound. hello 40 days and 40 nights....

I think for safety's sake we should strap bruce willis,arnold schwarzenegger, sylvester stallone and kevin costner into a rocket and shoot it towards the asteroid just to be safe (and to make sure that costner can't make any more movies)

[tandy ass]

Hypothetically, if we survived such an impact, what would it do to the earth's orbit around the sun and its rotation speed?

And can we stop the stupid posts unless they're really funny, such as launching Camira's at the comet?? :p

[jimmythe7th]

Ive heard the new BA Fords are heavy shooting one of them at the commet should stop it in its tracks:D. I dont think a asteriod of 1km size would have any effect on the earths orbit or rotation speed.

[Billzilla]

Back after a few days at work.
The big problem is that big enough sized asteriod (ie, not all that big at all really) hitting the ocean would not make a tidal wave as such, or even a tsunami, but a FAR more dangerous type of wave called a soliton.
A soliton wave does not disipate energy as it travels along, like any otehr normal wave, so it can travel all the way across the Pacific, break on the eastern shores of Aus, and completely destroy everything within about 5km of the beach.
Soliton or not, a free-standing wave in the cean cannot stand higher than 198 feet or 60.3 metres. The more energy they contain though, the faster they travel - It's quite possible that one could cross the ocean at over 400mph odd.
As they reach the shallower waters near the coastline, the energy gets all bunched up, and so the wave gets taller and taller, sucking in all the water around it.
A poor as some (many) Hollywood movies may be, the scene in "Deep Impact" where the huge wave hits the beach is probably not too far off the mark.

So yes, they're bloody dangerous.
