Massless objects always move at the speed of light (photos are massless). More important here is, that easy is not on a uniform motion, but rotating around sun, which is rotating around.... So even if they remain in their last motion, their path would cover from earth... But motion relative to what? The only special frame of inertia is the cosmic background, and that statement is still under debate
