Sit back and relax as we prepare to take a journey from the surface of the Sun and through our Solar system at the speed of light. You may want to pop the kettle on though because it’s going to take quite a long time. The Speed of light isn’t all that fast.

We start our journey at the surface of the Sun.

At just under a 300,000 km per second (that’s about 1.3 seconds to the Moon) the speed photons and other massless particles travel at is intensely slow on a cosmological scale. The incredibly talented Alphonse Swinehart¬†had the wonderful idea of creating an animation showing the actual speed a photon of light travels at after it has left the surface of the Sun.
