Saturn orbits the Sun at a distance of 9.59 AU (1,434 million km), with an orbital period of 29.45 years. Saturn's interior is thought to be composed of a rocky core, surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and an outer layer of gas.
The orbital period (also revolution period) ... or bodies with a similar density, e.g. Saturn's moons Iapetus with 1,088 kg/m 3 and Tethys with 984 kg/m 3 we get:
Orbital period (sidereal) 0.942 421 959 d: Average orbital speed. ... Mimas, also designated Saturn I, is the seventh-largest natural satellite of Saturn.
Many of them, such as Pan and Daphnis, orbit within Saturn's ring system and have orbital periods only slightly longer than the planet's rotation period. [46] The innermost moons and most regular satellites all have mean orbital inclinations ranging from less than a degree to about 1.5 degrees (except Iapetus , which has an inclination of 7.57 ...
Saturn – sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth . [ 1 ] [ 2 ] Although only one-eighth the average density of Earth, with its larger volume Saturn is just over 95 times more massive.
Dione (/ d aɪ ˈ oʊ n i /), also designated Saturn IV, is the fourth-largest moon of Saturn. With a mean diameter of 1,123 km and a density of about 1.48 g/cm 3 , Dione is composed of an icy mantle and crust overlying a silicate rocky core, with rock and water ice roughly equal in mass.
Saturn’s rings are seen as viewed by NASA’s Cassini spacecraft, which obtained the images that comprise this mosaic at a distance of approximately 450,000 miles from Saturn April 25, 2007.
Rhea has a nearly circular orbit around Saturn, but it is also tidally locked, like Saturn's other major moons; that is, it rotates with the same period it revolves , so one hemisphere always faces towards the planet. The moon itself has a fairly low density, composed of roughly three-quarters ice and only one-quarter rock.
