The actual relative sizes of the Solar System bodies [Les tailles réelles relatives des corps du système solaire].
In order to see the very dim grey trajectory of Pluto, one must multiply the actual radius of all celestial bodies by a huge factor (=5400).
And then, almost all planets (Mercury,the Earth,Mars,Jupiter,Saturn,Uranus) disappear "hidden" by the Sun -the big yellow sphere-
with the exception of Neptune -light blue- and obviously Pluto -dim grey-.

In order to display all the Solar System bodies one must change their radius arbitrary:
Each celestial body is colored according to its actual color:
the Sun (bright yellow),
Mercury (orange),
Venus (orange),
the Earth (dark blue),
Mars (red),
Jupiter (orange),
Saturn (yellow),
Uranus (cyan),
Neptune (light blue),
Pluto (grey).
