NASA is planning to launch a new mission in 2016 to find potentially hazardous asteroids and predict their impact threat to Earth.

NASA scientists have measured the orbit of asteroid with such accuracy that they were able to directly measure the drift resulting from a subtle but important force called the Yarkovsky effect.
