Solar System Scale Model Calculator

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 Calculate.

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).
