How do we find asteroids?

OSIRIS-REx presents a new 321Science video about the search for asteroids. This video explores how scientists discover asteroids. This is the first in our Targeting Asteroids! series, which will look at how scientists find asteroids, characterize them, and the role the OSIRIS-REx Target Asteroids! program plays in these efforts. 

And for more information on some asteroids that once discovered might need stopping, check out Bill Nye's explanation on AsapSCIENCE, Could we stop an asteroid?
