No Asteroid Armageddon |
<http://www.cnn.com/2004/TECH/space/12/29/asteroid.ap/index.html>
NASA bureaucrats today declaimed that the planet-destroying impact
with asteroid 2004 MN4 projected for Friday 13 April 2029 has been
idefinitely postponed.
"A quarter century lead time is inconsistent with emergency unlimited
funding," said the NASA Chief Assistant to the Thired Middle Associate
Temporary Administrative Liason. "We will readress the issue in our
five year plan written in 2024."
In the meanwhile NASA has begun negotiating for purchase of the
world's deepest mines in Idaho, Canada, Australia, and South Africa.

ROFL, so that's where all the dinosaurs went!

You can't destroy a planet with a 300m diameter asteroid.
(well, unless it's an extra-solar object coming in at hundreds of Km/s.)

not destroy it, but destroy the world economies.
A hit near any of the major cities would impact the financial markets
severely and cause stock market crashes. no food, riots, need to go deep
underground with cans of tuna, and candles.
what is the energy of a 300m coming in at 100,000 km/hr? assume Iron, or
depleted Uranium.
Where would you want it to hit? Bangalador, India?

Don't be bloody stupid.
There are no depleted uranium asteroids.
If it's rock, and hits at about 15Km/s, then it's about 700 megatons.
Where would you want it to hit? Bangalador, India?
Washington.
(NASA is planning to put a manned guidance system on the asteroid)
The chances of it hitting a major city is small.
50Km away, you're almost certain to come out OK, unless you get hit
by a big lump.

My calculator, from "The effects of Nuclear Weapons 1977" (great book the us
gov put out) indicates that the creator would be about 3 to 5 miles across,
for a 700 megatons (had to extrapolate some)
At 30 miles the over pressure would be 3 to 6 PSI wind speed would be 120
to 170 MPH
Not that bad on land surface burst. (I would want to be 100 miles away at
least)
Calculator says the crater would be about 1,500 to 2,500 foot deep
Nothing about fires started by compression wave etc.
Ocean hit would probably be far more damaging. Atlantic hit would flood
NYC, Boston, London etc.
Sounds like a good cause for funding another NASA study, "Where should the
Asteroid hit?"

Where do you find depleted Uranium asteroids?
Where would you want it to hit? Bangalador, India?
Where habshi is.
(NASA is planning to put a manned guidance system on the asteroid)
The odds of hitting a major city are small; the majority of the Earth's
surface is either sparcely populated or water, though an ocean hit
would cause a huge wave over a fair area.
Lots of "major" cities were pretty much destroyed in WWII; the world
continued.

You can destroy the biosphere. Imagine the tsunami.

No you can't.
800 megatons isn't a very big bang.
AIUI, it's a fair bit less than the yield of the recent earthquake for
which the tsuanami has 'only' killed 100000.
Serious, but not disrupting the biosphere.
