Which asteroids could crash into the Earth?
Prior to the detection of Yarkovsky effect on Apophis asteroid – scientists ruled out the possibility of the heavenly body crashing into the Earth in the year 2068. But, it is being reported that the asteroid is drifting away by 170 meters per year from its orbit due to Yarkovsky effect.
Can asteroids change course?
When the asteroid is still far from the Earth, a means of deflecting the asteroid is to directly alter its momentum by colliding a spacecraft with the asteroid. The momentum of the impactor is transferred to the NEO, causing a change in velocity and therefore making it deviate from its course slightly.
