due to orbital motion of planets and orbital motion of Earth Diurnal Motion Cause - rotation of Earth from west to east causes objects on the celestial sphere to appear to rise in the east and set in the west daily Day - period of time associated with complete rotation of Earth Sideral day - a 360 o rotation relative to background stars Solar day - a 361 o rotation relative to the Sun;
