This calculator is best suited for temporary re-locatable exhibits and will layout a two dimensional solar body array based on planetary locations as of a Base Year of January 1, 2014. It assumes circular co-planar orbits viewed from "below" the ecliptic plane with the planets moving in a clockwise direction. Average orbital velocities were used to calculate planetary positions in a selected Target Year. The User selects a Unit of Measure (feet, yards, miles, meters or kilometers) to facilitate a more compact array or a larger expanded array. Selection of Orbital Spacing allows the User to designate Relative spacing based on astronomical units from Sol or Equal orbital spacings which facilitates a more compact array. The Base Year Azimuth is the compass heading of the Sol-Planet azimuth measured from a Sol-Earth azimuth of zero degrees (due North).The User may select a Relative Azimuth which is a new compass heading of the Sol-Earth vector. New Sol-Planet azimuths are then calculated. Finally the User may specify actual GPS coordinates of the placement of the Sol image marker. The Green panel describes planetary layout of compass headings (Relative + Base Azimuths) from the Sol image marker to each respective solar body image marker and a Vector Length in the selected Unit of Measure from the Sol image marker to the solar body image. This layout may be done with a compass and measure wheel.The Blue panel describes the layout using x- (east is positive/west is negative) and y- (north is positive/south is negative) rectangular coordinates from the Sol image marker to each solar body image marker in the selected Unit of Measure. The Orange panel defines a layout using a GPS coordinates from the location of the Sol image marker.


An interactive educational experience to navigate an immersive exhibit of our solar system which may be used for geocaching games using GPS devices. The imagination is the only limiting factor.
