Thanks for the info! That's pretty cool. (My, Solar System, how big you are [img]/phpBB/images/smiles/icon_eek.gif[/img] .)

My trigonometry textbook offered directions for how you can map the orbits of the planets on a scientific (graphing) calculator. I only did the work for the four inner planets, but it was pretty cool! I was able to see why Venus is the brightest object in the sky - relatively speaking, its orbit is so very close to the Earth's! Mars' orbit, on the other hand, is pretty far out in comparison.

It is fun working out the solar system schematics in comprehendible measurements, isn't it? [img]/phpBB/images/smiles/icon_biggrin.gif[/img]
