Actually, thats a little misleading. It depends on what type of asteroid it is. If its a porus, or loosley held together bundle of small astroids, the
effect could be even more devistationg than if we left it whole. A stand off blast with one of these types of astroids would cause it to break into
smaller pieces. So your left with one big one, or 200 volkswagon sized ones. Also, I hadnt heard about painting one side white. Could you give a link
for that? I cant find anything on it.

I was under the impression that only a direct hit on a asteroid with a nuke would produce a "buck shot" type effect which would be worse. So the
stand off blast is considered to be the best chance we have right now by many scientist.
A stand off blast does not break up the asteroid as much as it just gives the asteroid a push in one direction.
As for painting a asteroid this works under the " Yarkovsky Effect" which is a term used to describe how an asteroid's trajectory can be influenced
by its heat radiation. This couls be done many ways and white paint is one of them. But we would need lots of warning time for this to work.
Painting the the asteroid's surface white. "That would make a big change to the way the object reflects sunlight. That might require a thickness of
only one millimeter or so (less than a 20th of an inch) over the entire surface.
I not sure how long it would even take to design a machine that could paint something this big in space. It would be a amazing task. I have seen this
concept on many shows talking about impacts. Heres a link I found about it.
