I just can't get over the evenly spaced-ness of the planets. I
   know it's for illustrative purposes but I'm like, "still not our
   planets... " smile emoticon I have a weird way of looking at it
   though: I think for science purposes, the heliocentric model
   makes more sense BUT for "humans living on Earth", a geocentric
   model *is* practical to learn. The reason? We're still here and
   that's what we see. In short, learning both should be required.
   Our eyes will not likely ever see the heliocentric model in
   reality.
