Uranus

Further into my investigations about the relative sizes and distances of celestial bodies, I realised that if you were as tall as the distance from the Sun to the planet Pluto, i.e. if you had the Sun on your head and Pluto at your feet, then Uranus would be right by your bottom, which seems quite appropriate.

Neptune would be at your knees, Saturn at your nipples, Jupiter on your chin and Mars at the level of your eyebrows; the Earth would be in the middle of your forehead. Of course, on that scale the Sun would be smaller than a grain of rice (about 1/5th of the width) and the Earth would be much smaller than the width of a human hair.
