Well first of all everything is relative, so no matter what your speed relative to "you" light well always be moving away from you at 299,792,458 m/s. Now from your perspective the light travels away from you at this speed because for every second that passes for you, no time has passed for the beam of light, the same for the people of the planet, this is why "c" is so important, it gives you something to compare everything else to.
