Photons, and anything else moving at c, don't really have a perspective.

An object moving at near c would experience almost no time at all during the journey. The distance between Earth and the Sun would, from its perspective, contract such that its near light speed movement allowed it to cross the distance much faster.

An astronaut takes off on a trip as a twenty year old. What is the farthest that he can he travel before he turns 30?
