The Moon's orbit is inclined by several degrees relative to Saturn's, so occultations will only occur when Saturn is near one of the points in the sky where the two planes intersect (both the length of Saturn's year and the 18.6-Earth-year nodal precession period of the Moon's orbit influence the periodicity).
The square of a planet's orbital period is proportional to the cube of the length of the semi-major axis of its orbit. ... Saturn 9.510 10759.2 7.43
Saturn orbit (Kronocentric orbit, named after Cronus, [3] ... A synchronous orbit around the planet Mars with an orbital period equal in length to Mars' sidereal day, ...
For instance, a small body in circular orbit 10.5 cm above the surface of a sphere of tungsten half a metre in radius would travel at slightly more than 1 mm/s, completing an orbit every hour. If the same sphere were made of lead the small body would need to orbit just 6.7 mm above the surface for sustaining the same orbital period.
The eccentricity of an orbit can be calculated from the orbital state vectors as ... where a is the length of the semi ... Saturn: 0.054 1: Luna (Moon) 0.054 9:
The Saturn I [a] was a rocket designed as the United States' first medium lift launch vehicle for up to 20,000-pound (9,100 kg) low Earth orbit payloads. [2] Its development was taken over from the Advanced Research Projects Agency (ARPA) in 1958 by the newly formed civilian NASA .
The use of long-exposure photographic plates made possible the discovery of additional moons. The first to be discovered in this manner, Phoebe, was found in 1899 by W. H. Pickering. [19] In 1966 the tenth satellite of Saturn was discovered by Audouin Dollfus, when the rings were observed edge-on near an equinox. [20] It was later named Janus.
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.
