Well, there are two issues here. (1) Correct proportions of the distances between objects (namely the planets, planetoids, and the Sun), and (2) the correct proportions of the objects themselves. The links (A) http://www.solarsystemscope.com/ http://www.solarsystemscope.com/ and (B) http://space.jpl.nasa.gov/ http://space.jpl.nasa.gov/ show correct proportionality in DISTANCES BETWEEN OBJECTS but NOT the objects themselves. For correct proportionality for both the distances and the objects themselves, see http://joshworth.com/dev/pixelspace/pixelspace_solarsystem.html http://joshworth.com/dev/pixelspace/pixelspace_solarsystem.h... The problem with http://codepen.io/juliangarnier/pen/idhuG http://codepen.io/juliangarnier/pen/idhuG is that both the distances between objects and the objects themselves are not proportionally correct.
