    The speed that the laser beam approaches Earth with is 299792458 m/s

    Explanation:

    The speed of light in any inertial reference frame is always c=299792458 m/s or 3*10⁸ m/s. This is because the speed of light is constant throughout the universe and this was proved in Einstein's theory of general relativity.
