Ok here is a question for everyone in the next decade or two if one of NASA's satellites spots an asteroid traveling at 14,000 mph and is exactly 2 light years away from earth how long will asteroid take to get here?

(Note): When I mean in the next decade I mean that NASA could spot an incoming object 2 or more light years away within 120 seconds, and another 5 seconds of sending the data of the incoming object back to earth.
