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.
