Period rotacije

U astronomiji, period rotacije nebeskog objekta vreme je koje je potrebno da se završi jedna revolucija oko svoje ose u odnosu na pozadinske zvezde. On se razlikuje od solarnog dana planete, koji obuhvata dodatnu frakcionu rotaciju potrebnu za smeštaj dela orbitalnog perioda planete tokom jednog dana.
