A Sense of Perspective

Here's a recent video of several friends putting together a scale model of the Solar System out on the Black Rock playa.  With the Sun represented by a meter-and-a-half balloon and the Earth by a marble, the entire model's seven miles across the diameter of Neptune's orbit.  Had they included Pluto, it would have taken another four miles.

It is good to be reminded of these things occasionally.
