The Earth will have a close encounter Wednesday with a massive asteroid nicknamed "The Rock." NASA first learned about it three years ago, and it is the largest to pass by Earth since 2004. CBS News science and futurist contributor Michio Kaku joins "CBS This Morning" to discuss how the asteroid will not affect Earth, although it does show the dangers of nearby objects.
