Solar System Scale Model Calculator

Calculate the scaled planet diameters and planet-sun distances for a solar system model.
Examples: Set Scale 1 : 100000000  OR  Sun Diameter = 10 cm  OR  Neptune Distance from Sun = 1000 ft,
then choose options and press Calculate.

SCALE 1 : OR =

You can save the KML file and open it in 3D map applications like Google Earth.
If you download a KML file, save it with a file name ending with .kml (not .kml.php).
