Nice but it is too jaggy to be an asteriod. Aren't they fairly smooth?

Can't really say. I've never actually seen one.
I would think that given the number of impacts
that they incure in the asteroid belts they would
have very little chance of being smooth. Smooth
would imply a wearing down by friction which does
not occur in space.
Oh well next time I get a chance to see one up close
I'll change my model accordingly :)

That's a really amazing asteroid! It may be the best CG asteroid I've ever
seen (well, outside Armageddon...)
A couple of comments.
From pictures I've seen of large asteroids, the craters seem to be filled up.
Probably with dust and leftover bits from collisions with other asteroids. I
mean the gravity's tiny, but not totally gone.
Craters on real asteroids might look a little eroded since most impacts would
be with asteroids that are really tiny. They would chip away at the landscape
and create more dust to fill the craters!
I recently read an article in Nature which was about what a massive impact
would do to an asteroid (If I remember right, they were simulating a rock the
size of a house impacting at 20,000 mph). Well, the bottom line was this. It
looks like any impact that could make a crater of any size (>0.25 the size of
the asteroid) would totally shatter it! But there is that moon of Jupiter or
Saturn with a crater that makes it look like the death star!
Anyway, just tell everyone it's artistic license.
In Him,
Ben Birdsey

If you still have the time <g>
(I'm referring to the film Deep Impact)

When other asteriod smash into it, they melt( if they are made out of
metals or solid rock) when they cool they are smooth, kind of. Like the
moon it is smooth, or looks smooth from dust. I'm not sure but most
pictures I've seen of asteroids are fairly smooth. They have craters
though.

like what looks like a submarine in the Pearl Harbour scene on the IRTC
page?
Someone told me that there were no submarines at Pearl at the time of the
attack (He was a WW2 vet that served in the south Pacific at the time)
