NASA was recently tracking a large asteroid, known as the "city killer," after finding a small chance of it hitting Earth in 2032. NASA says it "no longer poses a significant threat" in an analysis, but it's not the only space rock astronomers are monitoring. Kris Van Cleave shows how "asteroid detectives" and "planetary defenders" are trying to protect Earth from a potential disaster.
