Automobile sized asteroid heading for earth?

[Baked]

Yawn... let me know when a Texas size chunk is incoming.

Try this for size

Holy shit.

A 1km iron asteroid hitting at a 40 degree angle at 50km/sec into sedimentary rock would leave a 677m deep by 15,687m wide crater.

That's some damage. For "only" 1km...

i did the worst case scenario and it still wouldn't wipe out the earth

Well if a larger one - 1km or more - is en route hopefully the warning time is a bit longer. :Q

Yeah no shit. Man, that would be insane.

Tomorrow's News:

Car-sized asteroid was only first of many - asteroids held in group by asteroid the size of England, to hit Thursday night. Nice knowing you Earth.

Sweet happy 22nd birthday to me 🙂

Just because the hole isn't the size of Earth, or reduce it to rubble doesn't mean it won't wipe out life on Earth from the after-effects....

This happens all the time. They usually just land out in the desert, ocean, or disappear down a mid sized chimney. 😛

Mid-sized chimney? If it can swallow car-sized asteroids, that brings the hotdog-hallway imagery to another level.

"It's a chimney, not a clown car!"

aren't there discussions out there which say that asteroid impacts are greatly over-exaggerated?

ie no nuclear winterish from an asteroid of 1km size

That's probably true, but it would still leave one hell of a hole in the ground, and make some nice fireworks.

It would have to be a really large asteroid to create a nuclear winter, I would think. It would take a lot of material to block out the sun.

Yes, but if we had a proper space program, we'd get plenty of notice to send a REAL spacecraft out to push that civilization killer out of the way.

A 10km dense rock asteroid hitting at a 30 degree angle at 50km/sec would leave a 1,130m deep by 85,803m wide crater.

:shocked:

That would probably be noticeable. 😉 lol

 

[FeuerFrei]

It's about a 99% chance it'll enter the atmosphere, not impact the ground.

 

[Rubycon]

500km from impact site:

Clothing ignites

Much of the body suffers third degree burns

Newspaper ignites

Plywood flames

Deciduous trees ignite

Grass ignites

Multistory wall-bearing buildings will collapse

Wood frame buildings will almost completely collapse

Multistory steel-framed office-type buildings will suffer extreme frame distortion, incipient collapse

Small bridges will collapse

Steel frame bridges will collapse

Glass windows will shatter

Cars and trucks will be largely displaced and grossly distorted and will require rebuilding before use

Up to 90 percent of trees blown down; remainder stripped of branches and leaves

That's like dropping a matchstick on a table saw blade. :laugh:

But... it'd be the most useful project ever done by the ISS 🙂

Google Earth would be more popular. lol

What size asteroid is that?

This is true...

Yes if it worked like a real saw does. An oak plank dropped onto a large carbide tipped blade on a big (5hp+) machine will turn that timber into a deadly arrow. :Q

What size asteroid is that?

Max iron, max velocity, 90 degrees into water at max depth.

Rosie O'Donnell size?

until it's gets MUCH bigger than a house , they are not much of an issue, and considering 70% of the earth is covered by water and only a small fraction of the land is occupied it's a pretty small chance of anyone getting hurt by an asteroid that doesn't cause massive distruction

...Except everyone living on the coast of said ocean.

I don't even want to know what kind of tsunami even a 1km asteroid would create. :Q

Now one thinks this is even remotely scary?? This could be the end of the world!


...We need to send Bruce Willis into space, immediately!

Nope. But ask the dinosaurs if getting hit by something that wouldn't destroy the planet is okay. A giant space rock doesn't need to come close to destroying the planet to be able to destroy all life larger than bacteria.

I think you'd have a better chance at saving a pirated copy of Iron Man to a Snickers bar shoved in a BluRay drive before that happens. 😉

maybe, but a 15km asteroid is going to displace enough dirt and debris to shield the entire earth from sunlight?

hey hey... they've done...

um...

oooo ooo, they've done some science stuff up there, right?! yeah, science!
