# Solar System Scale Model Calculator

## Solar System Model Inputs

Calculate the scaled planet diameters and planet-sun distances for a solar system model.
Enter scale or diameter or distance, select to show table and/or map below, select options, then press Calculate.
Examples:    Scale 1 : 100000000   or   Sun Diameter = 10 cm   or   Neptune Distance from Sun = 1000 ft.
