s aturn in Your Horoscope
Saturn, the taskmaster, is the principle of self-preservation and basic security. The location and condition of Saturn is an extremely sensitive and important consideration. In many cases Saturn can be the single most determining factor in the entire horoscope. Self-preservation often takes precedence over ego fulfillment (the Sun), emotional gratifications (the Moon), pursuit of ambitions (the tenth house), development of the personality (the first house), or indulgence in pleasures, love or sex (the fifth house). If the native does not solve this requirement of basic security, none of the other matters can have any permanent satisfaction.

Where Saturn is by house indicates the area of experience where the native's basic security is most vulnerable. The requirements of this house must be given top priority before the native can turn his attention to higher matters. Sometimes only a quasi compromise is achieved, which, if shaky enough, can undermine the native's best efforts all his life.

Rings
Rings are 270,000 km in diameter, but only a few hundred meters thick. Particles are centimeters to decameters in size and are ice (some may be covered with ice); there are traces of silicate and carbon minerals. There are four main ring groups and three more faint, narrow ring groups separated by gaps called divisions.

Clouds and Spokes
Several dark spoke-like features can be seen across the broad B ring (left of planet). The moons Rhea and Dione appear as dots below and below left of Saturn, respectively. Voyager 2 made its closest approach to Saturn on August 25, 1981.

Global Dichotomy
The leading hemisphere of Iapetus is covered by extremely dark material, whereas the trailing hemisphere is covered with bright material. This dichotomy puzzled the discoverer, astronomer Giovanni Cassini, who noted that the satellite was visible only from one side of its orbit. Two models have been proposed to explain this. The first proposes that dark material from Phoebe, a dark exterior moon, falls onto Iapetus from orbit. The second model says that the dark material erupted from the interior of Iapetus into a low area in the leading hemisphere.

Irregular Body
Scientists believe that this small irregular satellite may once have been a piece of a larger satellite. Hyperion measures approximately 370 x 280 x 225 km (229 x 174 x 140 mi) and orbits outside of Titan.

Obscure Titan
Titan's hydrocarbon-rich nitrogen atmosphere scatters sunlight in a forward direction over the limb around the entire disk. The surface of Titan is obscured due to a deep cloud layer. The diameter of Titan is 5150 km (3200 mi).

Water Ice
The density of Saturn's moon Rhea suggests that it is largely made of water ice with a small proportion of rocky material. Note that the ancient impact scars that ripped through the ice early after the formation of the solar system are still preserved to this day.

Full Disk
Impact craters are may be visible records of the collision of cosmic debris. On Dione, the largest crater is less than 100 km (62 mi) in diameter and shows a well-developed central peak. The sinuous valleys may have formed when faults broke the moon's icy crust.

Smooth Crust
In this image of Saturn's fourth large moon, Dione, the trailing hemisphere is visible. This region was protected from billions of years of impact-gardening, which obliterated old surface features in the leading hemisphere. Icy fluids escaped to the surface through breaks in the crust and formed giant crisscrossing, wispy, bright marks on the exterior.

Impact Craters
Tethys is approximately 1100 km (684 mi) in diameter and is densely populated with impact craters. One of them is surrounded by a hummocky ejecta blanket. Ithaca Chasma stretches from left center up toward the crater, covering three quarters of the circumference of Tethys.

Bright Satellite
The surface of Enceladus resembles that of Jupiter's satellite Ganymede. Some areas are smooth and uncratered while others contain impact craters up to 35 km (22 mi) in diameter. Linear sets of grooves tens of kilometers long traverse the surface and are probably faults resulting from deformation of the crust. The uncratered regions are geologically young and may indicate that Enceladus has experienced a period of relatively recent internal melting. The satellite is about 500 km (310 mi) in diameter and has the brightest surface of any of Saturn's satellites.

Cataclysmic Impact
Mimas, the innermost of Saturn's larger moons, was nearly shattered by a cataclysmic impact. From observing Mimas' crater Herschel, scientists speculate that the inner satellites of the outer planets have, in fact, been shattered and gravitationally reassembled many times in their geologic history. Herschel's walls are approximately 5 km (3.2 mi) high, parts of its floor measure 10 km (6.2 mi) deep, and its central peak rises 6 km (3.7 mi) above the crater floor. The diameter of this moon is 394 km (244 mi).

Saturn's Moons
Saturn and two of its moons, Tethys and Dione, were photographed by Voyager 1 at a distance of 13 million km (8 million mi). The shadows of Saturn's three bright rings are cast onto the cloud tops. The limb of the planet can be seen easily through the 3500 km (2170 mi) wide Cassini Division, which separates the A and B rings. The view through the much narrower Encke Gap, near the outer edge of the A ring is less clear. Closer to the planet is the faintest of Saturn's three main rings, the C ring or crepe ring, barely visible against the planet.

   

i n Roman mythology :
s aturn was a god of fertility and agriculture
. He was commonly identified with the Greek god Cronus (Kronos), and there is an interesting story that explains how Cronus was transformed into Saturn.
The tale told by the ancient Romans is that Cronus departed from Greek soil when he and his Titan allies were conquered by the Olympians. In Italy, the name of this god was changed from Cronus to Saturn. As Saturn, the god fled to Latium in an attempt to escape from the wrath of his son Jupiter.

Saturn demonstrated his leadership abilities and became a ruler in Latium. As a king of Latium, Saturn was responsible for the remarkable achievements of this legendary time, a time which was thought of as the Golden Age of ancient Italy. According to the myth, Saturn introduced agriculture to his people by teaching them how to farm the land. For this reason Saturn was thought of as a god of fertility and agriculture.

There was even a Roman festival named after Saturn - the Saturnalia. This festival was celebrated during the winter, and it was a time of gift giving, feasting, and merriment. Indeed, the Saturnalia is an appropriate festival to Saturn, for it appears to evoke the prosperity and peace of Rome's mythical Golden Age.

In early myth, Saturn was associated with the obscure Italian goddess Lua. However later legends claim that he was married to Ops, a Roman goddess of the harvest who was identified with the Greek goddess Rheia.

The name Saturn is sometimes spelled Saturnus.
