<P> Titan orbits Saturn once every 15 days and 22 hours . Like the Moon and many of the satellites of the giant planets , its rotational period ( its day ) is identical to its orbital period ; Titan is tidally locked in synchronous rotation with Saturn , and permanently shows one face to the planet , so Titan 's `` day '' is equal to its orbit period . Because of this , there is a sub-Saturnian point on its surface , from which the planet would always appear to hang directly overhead . Longitudes on Titan are measured westward , starting from the meridian passing through this point . Its orbital eccentricity is 0.0288 , and the orbital plane is inclined 0.348 degrees relative to the Saturnian equator . Viewed from Earth , Titan reaches an angular distance of about 20 Saturn radii ( just over 1,200,000 kilometers ( 750,000 mi ) ) from Saturn and subtends a disk 0.8 arcseconds in diameter . </P>
