Sun and 9 Planets to Scale remix

thingiverse

Remix of https://www.thingiverse.com/thing:1430614 using the original OpenSCAD file I added the earth's moon, adjusted the scale for 20cm long dimension(was 17cm) and carved out saturn's rings to they were not a disc. This shows the sun and 9 planets to scale. Earth is the 3rd planet from the left only planet with a moon. Distances are not represented to scale, only sizes are. 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. enjoy ======== for those who would like the geometry: reference: pages 6 and 7 from https://www.nasa.gov/pdf/622145main_SSML1Answr.pdf diameters in kilometers d_mer_km = 4878; d_ven_km = 12104; d_earth_km = 12755; d_earthmoon_km = 3476; d_mar_km = 6790; d_jup_km = 142796; d_sat_km = 120660; d_sat_rings_km = 2 * 136775; d_ura_km = 51118; d_nep_km = 49528; d_plu_km = 2370; d_sun_km = 1392600; sf_r = 2.50; //original was 2.25; // scale 2,250,000,000,000 UPDATE: planets_9a.scad - made adjustments for better scaling. ex: adjusted planets spacing based sun radius( r_sun/80 ), ring gap and ring width based on r_sat
