Plot planet positions using polar graph paper or the provided activity sheet.

This is a coordinate system which allows for the plotting of a planet position along its orbital path using degrees (0o to 360o) of heliocentric longitude. Once plotted the orbital position of one planet could be compared with that of another planet. Or the relative orbital speeds of an inner planet could be compared with that of an outer planet.
