Sidereal Period versus Synodic Period. 1  Measuring the motion of the Moon around the Earth relative to the distant stars leads us to what is called the sidereal period. 2  Measuring the motion of the Moon around the Earth relative to the Sun leads us to what is called the synodic (pronounced si-nod-ik) period.
The sidereal period is regarded as an objectâs orbital period. The synodic period is the required time for an object to resurface simultaneously in respect to two other objects. An example would be the Sun, Moon and Earthâs linear relationship.
