Sun and Planets to scale update 1.28.2018

thingiverse

This shows the sun and planets to scale. Earth is the 3rd planet from the left. The diameter of Jupiter is 11.20 times the diameter of earth. It looks even larger because the volume of Jupiter is 1,403 (=11.2^3 cubed) times the volume of earth. In file planets_5_160415aa.stl I have corrected the diameter of the sun per stefanpwinc's comment. this file does not include pluto update 1.9.2018 file planets_(21)_w_pluto_r1_180109.stl includes pluto per keebie81's and wbphelps' request. Pluto's diameter = 2370 km. Our moon's diameter = 3476 km. So pluto looks very small.
