When I posted about visualizing the speed of light a couple of days ago, one of my readers pointed out another site that did a great job helping visualize the size of the solar system. If the moon is one pixel wide, what are the various sizes of the objects and their distances from each other. It starts out with the sun and you can scroll to the right to start getting to the planets. There is also a “speed of light” button on the right lower corner, the “C” button, which turns on auto scroll at the speed of light. Thanks, PS, for pointing out this site to me.
