Instead, photons take a "random walk" on their way out of the Sun. They travel about 1 millimeter (or 0.001 meters) before getting scattered in a random direction. It takes a photon roughly 5 x 1023 "steps" (each 0.001 meter in length) to finally get out of the Sun. How far does a photon end up walking by the time it reaches the Sun's surface? 

Given the actual distance traveled during a random walk, how long does it take photons to escape the Sun if they are traveling at the speed of light? Give your answer in years. After photons escape the Sun, how long does it take them to travel 5.2 AU to reach Jupiter? Give your answer in minutes.
