Moving it one one hundredth of a degree can make it move by thousands of km after it travels a several million kilometers. (for instance, if would knock it off course by about 6108 km if our rockets moved it at 35,000,000 km out).
So landing on a life-extinguishing asteroid as it's barreling through space and strapping 'X' amount of rockets to it is "very easy"? You've been watching to many SciFi films, dude.
