Thought I would pass along a link to a very well made video of a 100km asteroid hitting the and what the results would be. have a look and then take a moment to give thought.

I believe it belongs in this section of the forum.

This is not realistic. The effect shown looks more like the result from a 500Km asteroid.

The video won't load for me.

Why is the rock all glowy at the start, and why is there all that whooshy noise in space?

Someone who understands Japanese will have to tell us exactly what's supposed to be going on, but my guess is that someone's attempt to divert it was unsuccessful.

One article I read recently suggested that an above-surface blast of one or more nuclear devices would be the best way to try to divert incoming asteroids. The explosion would provide sideways thrust and, since the forces are all on one side of the body, it'd be less likely to fragment the body into many pieces than would a sub-surface blast like that used in the movie Armageddon.

As for the sound, well, that's just artistic license.

hi as to it wont load the vid is in flash ( windows)

(linux) you know where and how

The planettessimal is an anime and in tridithional style --the effect glowing and noisey ,etc..

a nuke blast would only be effective for a nickle/iron astroide and not for the stoney (carbonish condrite) -? spelling?
the stony type will fragmentate into a whole lot of "small" ones ( the shotgon effect)

still if we had aprox. 5 to 10 years to impact then landing a VERY BIG rocket on it is the best bet to move it

but it looks cool
nice find

While I was watching it the only thing that crossed my mind was "Where are the Japanese robots to save the planet" But yes this looks over climactic for a 100km asteroid. 500km would be more accurate IMO

Is it me.. or did they forget the steam, the rush of atmosphere(wild storms, atmospheric waves e tc), resulting earthquakes, tsunamis, Missile launches (unfortunately, couldn't that be a problem) or waves of land as the thing obviously, smashed pretty deep into the crustt. What about tidal effects before it hit the Planet? ... picky picky.. i know

it's an anime what do you expect

it dose look quite nice / artistic

Since this evidently is a Japanese anime, not a scientific prediction of what might happen, and since nobody seems to be interested in discussing any of the physics that might be related to such an event, I'm moving this thread to purgatory.
