There is a misconception, geocentric and anthropomorphic, common to the large majority the the earthbound, which causes them to visualize a planetary system stereoscopically. The mind's eye sees a sun, remote from a backdrop of stars, and surrounded by spinning apples -- the planets. Step out on your balcony and look. Can you tell the planets from the stars? Venus you may pick out with ease, but could you tell it from Canopus, if you had not previously been introduced? That little red speck -- is it Mars, or is it Antares? Blast for Antares, believing it to be a planet, and you will never live to have grandchildren.
