# Thread: Meteor the size of Texas

1. ok...looks like nobody has read my post on page 4, and i am glad, because its pretty stupid anyway, but it proves the fact, that earth will be destroyed. i played with http://www.purdue.edu/impactearth

Real texas
diameter: 1270 km
weight: 53,820,000,000,000 kg
earth = destroyed, nothing left, i mean NOTHING!!!! the earth is no more, n o t h i n g l e f t! ok, so what? i "thought" about a smaller meteor and created Bob, the Meteor.

diameter: 750km
weight: 50.000 kg
impact angel 45 degrees
impact velocity: 11km/s
target type: Water of Depth 10.000m
Distance From Impact: 19.999

so, remember, bob is smaller, and lighter then texas!!!

Energy: 6.68 x 10^29 Joules = 1.6 x 10^14 MegaTons TNT
Dmg: The Earth is completely disrupted by the impact and its debris forms a new asteroid belt orbiting the sun between Venus and Mars.
100 percent of the Earth is melted
Crater: Final Crater Diameter: 74100 km
thermal radiation: The fireball appears 2370 times , Thermal Exposure: 1.5 x 10^15 Joules/m^2, Duration of Irradiation: 798 hours,Radiant flux (relative to the sun): 521000
Seismic: Richter Scale Magnitude: 16.3
airblast: The air blast will arrive approximately 16.8 hours after impact,Peak Overpressure: 2220000000 Pa = 22200 bars = 315000 psi,Max wind velocity: 37900 m/s = 84800 mph,Sound Intensity: 187 dB (Dangerously Loud)

And for the lolz the texas data too^^

energy: 3.49 x 10^39 Joules = 8.34 x 10^23 MegaTons TNT (does this mean 83.400.000.000.000.000.000.000.000 oO?)
Dmg: 100 percent of the Earth is melted,Depending on the direction and location of impact, the collision may cause a change in the length of the day of up to 1870000000 hours.
Crater: Final Crater Diameter: 59700000000 km (Earth is vaporized...)

So we are fuc***. But we could send Chuck Norris to destroy the meteor, he would probably die, but we know, we did everything we could....

Yes it would.
There's this big one coming at is us in ten years or so. It had some 1:45 000 chance of hitting us if it gets pulled in by our gravity.

They had deviced a plan to move it though, it was quite smart.

3. Topper, I don't think you're entering that information correctly at all. You're entering the weight of the object in the mass. Your test objects have the density of some of the most dense objects in the universe.

oh... sorry

5. Depends on speed and impact location, but in most situations yes. We will have plenty of time to say our goodbyes and have mad sex parties though.

6. An impact from a meteor the size of Texas would evaporate every drop of water on earth, turn the atmosphere into an inferno as all the oxygen is comsumed and, more than likely, turn the entire crust of the planet into molten rock. The earth would be steralised down to the bedrock and would take millions of years to cool to anythin like the current temperature. The gasses of the atmosphere may well be blasted into space by the shockwave. As most of the gas / water is thought to have arrived on earth in the form of comets, the planet may never recover an atmosphere as cometery activity is much less than it was in the early days of the sola system.

So, no survivors, not even single cell organisims, viruses or bacteria.

As to how often this has happened in the history of the earth? Take a look at the moon, count the craters. There are A LOT. The moon is younger than the eath and has a weaker gravitational pull, therefore it is safe to assume that the earth has been hit more times than the moon, whivh means the earth has been hit by asteroids / comets A SHIT LOT.

People would survive, no question about it.
No. No. False. Wrong. And No.

In fact, No.

And even then, No.

An asteroid the size of Texas, assuming its only a single KM thick, would have the same KE of 11,287,325,000,000 Hiroshima Bombs.

That's right, 11.2 Trillion.

For perspective, thats ~1600 for each person on the planet.

Now, granted, it would only hit one side of the planet. Lets think about that for a second.

It would be travelling at ~25 km per second. That means it would take ~ 4 seconds once it hits the atmosphere for it to hit the ground.

Now, it would likely land in the ocean, flash boiling at least 20% of the planet's water. That alone would cause a dramatic shift in Earth's environment, which would result in massive chaos.
Fortunately for us, the Asteroids impact would cut through the Earth's crust like a fucking sword through milk. And by fortunate for us, I mean we would die instantly instead of slowly and painfully.

Of course, if we're on the other side of the planet, it's worse.
See, the Asteroid will have destroyed the atmosphere, flash boiled a large portion of the Earth's breathable atmosphere and water, and flung enough ash and dirt into what's left of the atmosphere to block all sunlight for a million years.

Even if some people managed to survive the initial impact, the planet would become so cold we would freeze if we came close to the surface. Plants, Animals, Trees... everything we need to survive would die out. We would die slow, painful, torturous deaths.

TLDR: If it hit, we'd be fucked.

Hell, if one does come, I hope it lands right on top of me... it'll be the best way to die.

And just think of the view. Texas coming at you at 25km/s.

I sware to god if I see people say this one more time i'm going to go Al Gore style and widely popularise this issue and inform people.

This just made me remember something my 6th grade science teacher said.

He said he hates all the movies where meteors crash into the earth and people watch their own death, because the meteor is traveling so fast you literally wouldn't be able to see it and the next second you would be dead.

Ohhh 6th grade

10. I would survive in my anti-Meteorite bunker for decades.

What a wonderful existence. Better to die outright.

i personally would hide under a bed in the Legion of Doom Headquarters.

And unless someone is qouting some scientific source i wouldnt believe too much of what people say on a forum.
What does that have to do with the population being wiped out? Microorganisms survive absolute zero too.

A Texas sized meteor would wipe out all but maybe the single celled organisms. In the 00.01% chance anything did survive the initial impact, the earthquake, airblast, potential axis shift (change in pretty much everything) would take care of it. It wouldn't destroy (explode?) the planet, the planets are pretty tough. It would be forever scarred with a massive crater, but it would remain intact.

In reality though, something that large would never get close enough. It'd get pulled towards Jupiter or Saturn most likely.
I actually meant 120x, but whatever. The point is still the same, whether the meteor is a mile wide or 720 miles wide, all life (excluding microrganisms) is no more.

Because the Europeans don't have countries large enough to measure it. :P But in Canadian, 1 Texas ~= 1 Alberta.

No probably not. There would still be microbial life deep in the ocean that rely soley on the nutients provided by volcanic vents in the ocaen floor. Other than that... yes

16. we most likely have a base on the moon/mars or whatever when that happens, so just the ppl on earth are really screwed, but mankind would survive
