Re: Or an anti-matter beam!
Why anti matter, when a laser beam would do the same? Or for that matter, drop a lot of white paint on one side to change its albedo and let solar radiation shove it to a different orbit that just misses Earth. If you've got time, that's probably the easiest option. Well it is, depending on how hard it is to cover a large asteroid with paint.
