<P> Diurnal motion ( Latin : diurnus , lit . ' daily ' , from dies , lit . `` day '' ) is an astronomical term referring to the apparent daily motion of stars around Earth , or more precisely around the two celestial poles . It is caused by the Earth 's rotation around its axis , so almost every star appears to move along a circular arc path called the diurnal circle . The time for one complete rotation is 23 hours , 56 minutes , and 4.09 seconds ( 1 sidereal day ) . The first experimental demonstration of this motion was conducted by Léon Foucault . </P>
