Physical Data
| Average Distance from the Sun | 1.427 x 109 km = 9.529 AU |
| Aphelion | 1.507 x 109 km |
| Perihelion | 1.347 x 109 km |
| Orbital Velocity (ave.) | 9.64 km/s |
| Sidereal Period | 29.458 Earth years |
| Rotation Period | Equatorial: 10h 13m 59s
Internal: 10h 39m 25s |
| Tilt of Rotation Axis | 26.7 degrees |
| Equatorial Diameter | 120,540 km |
| Mass | 5.69 x 1026 kg |
| Density (ave.) | 690 kg/m3 * |
| Escape Velocity | 35.5 km/s |
| Surface Temperature (ave.) | -180oC = -292oF = 93K |
* Saturn's density is less than the density of water. So, if you could find an ocean big enough, Saturn would float!
-Definition: Astronomical Unit (AU) - the average
distance between the Earth and the Sun.
-Definition: Perihelion - the minimum distance
from the Sun.
-Definition: Aphelion - the maximum distance
from the Sun.
-Definition: Sidereal Period - the actual time
it takes for Saturn to orbit the Sun, with respect to the background stars
and not the position of the Sun.
