Looking up at the night sky, it's always amazing how big the moon looks at certain times.   Now just imagine that other planets were just as close as the moon in the night sky.  I watched this video tonight and it really brings home how small our moon is and how awesome our planet would look from space.  Now you have to suspend your knowledge of how gravity works, and things like that, but it's interesting either way.  The most polarizing part of the video is when Jupiter goes across the night sky.  Really brings the point home!
