Saturn


Saturn is the 6th planet from the Sun. The planet is classed as a gas planet. saturn derives its name from the Roman god for God of Time. Saturn has been known for centuries ever since people looked to the stars and noticed a star moving across the sky.The mass of the object is 568.46. The equatorial radius of the planet is 60268 whereas the volumetic mean radius is 58232. The Mean Density of the planet is 687. The surface acceleration of the planet is 8.96. The time the planet takes to revolve round the Sun is 10759.22 days or roughly 29.5 Earth Years. The length of a day on the planet is 10.656 hours, i.e. the time it takes to revolve once on its axis. The average temperature of the planet is -134K/-139C. The surface pressure of the planet is >1000bars.

saturn is about 1433500000.0km from the Sun. The Orbit Eccentricity is 0.0565, that is how much the orbit deviates from a circle, between 0 and 1. The Orbit Inclination is 2.485, that is how much the orbit deviates from a circle, between 0 and 1. The volume of saturn at the equator is 82713. The escape velocity, the speed which is need to break free is 35.5. The surface gravity of saturn is 10.44 compared to Earth which for purpose of this site is 1. The following gasses can be found in the saturn's atmosphere : Molecular hydrogen (H2) - 96.3% (2.4%); Helium (He) - 3.25% (2.4%)\n. More information and the source for the moon can be found at N.A.S.A.

Saturn is most famous for its rings and was for a long time considered to be the edge of the solar system, that was until Sir William Herschel discovered Uranus. Orbiting round the planet is Titan which if it wasn`t for its atmosphere wouldn`t stand out. Titan is the only satellite moon in the solar system known to have an atmosphere. The rings were first noticed by Galileo Galilei after he had made the first telescope.



Saturn

The first artificial visitor to Jupiter was the Pioneer 11 space probe back in 1979 on its journey out of the solar system. Since then, the Voyager probes have flown by and most recently the E.S.A. (European Space Agency) sent the Cassini-Huygens craft to look closer at Jupiter and its biggest moon Titan. The Cassini-Huygens probe is two parts, one to probe the planet from above, the other is to land on Titan. Both have successfully completed their original parts, arrive and land. The Cassini voyage round the planet continues. Huygens is named after Christiaan Huygens, the Dutch astronomer who discovered Titan. The Cassini part of the probe is named after Giovanni Domenico Cassini who discovered a number of Saturns moons and the separation of the rings.

Saturn Legend

The inspiration for naming Saturn came from the Roman God of the same name. Saturn was known as the God of Agriculture, Liberation and Time. Saturn was also the father of Jupiter of which is the planet that is closest to Saturn and is closer in than Saturn. The Greek equivalent of Saturn was the Greek God Cronus. Saturn`s wife was known as Ops and likewise, the wife of Cronus was Rhea. Saturday, the seventh day of the week is named after the Saturn. ref:Crystal Links
