Day 76: Planet Walk exhibit

The alternate planet walk is complete. It displays the sun and planets to scale in both size and distance apart. The inner planets out to Mars look comfortably grouped, though almost too small to see. But it is a long walk to the outer planets. The vertical bars in the background represent light moving out from the sun. To just reach Mercury takes it about three minutes.

There is a notecard available at the arrival point which contains a light speed indicator which, when worn, shows you how many times the speed of light you are moving at.

The exhibit can also be reached by an Anywhere Door on the ground floor of the observatory.
