The planet Saturn is composed of
hydrogen, with small proportions of helium and trace elements.[10]
The interior consists of a small core of rock and ice,
surrounded by a thick layer of metallic hydrogen and a gaseous
outer layer. The outer atmosphere is generally bland in
appearance, although long-lived features can appear. Wind
speeds on Saturn can reach 1,800 km/h, significantly faster
than those on Jupiter. Saturn has a planetary magnetic field
intermediate in strength between that of Earth and the more
powerful field around Jupiter. |

Saturn is the sixth
planet from the Sun and is the second largest in the solar system
with an equatorial diameter of 119300 km. |

Saturn the second most
massive planet, and the most distant planet known to the ancients, is one of
the most beautiful sites in the Solar System. It is impossible for us
now to know at what time the heathen mythology began; but it is
certain, from the internal evidence that it carries, that it did not
begin in the same state of condition in which it ended. All the gods
of that mythology, except Saturn, were of modern invention. |

Astronomers have spotted 12
tiny new moons circling Saturn. The observations could help
scientists understand how such satellites become snagged by
gas giants. A team of astronomers from the University of
Hawaii and the Carnegie Institute of Washington first spotted
the dozen using the Subaru telescope on Mauna Kea, Hawaii on
12 December 2004. Their observations were part of a broader
hunt for irregular moons so called because their orbit is far
from circular or highly inclined with respect to their
planet’s equatorial plane. In 1772, the famous mathematician,
Joseph Louis Lagrange, discovered that, in a system which
consists of a satellite in orbit around a larger body, there
are five positions at which a third body can also maintain an
orbit. These positions are now called Lagrange points after
him.Saturn
has a similar nature as Jupiter, it is a giant ball of liquid
hydrogen. Astronomers saw through a telescope and Saturn
appeared as a coulered ball with darker belts
and lighter zones which follow a similar pattern to
those of Jupiter. The rotation periods of Saturn
Equatorial Region has an average of plus/minus 10h.
14 minutes. Saturn is soo far from the sun that its
atmosphere is of course colder than the one of
Jupiter. The temperature above the clouds is minus
170 degrees compared to those of Jupiter being minus
120 degrees. The atmosphere is almost similar
comprising mainly Hydrogen- Helium and also Methane
and Ammonia are present. Titan, one of the largest
moons of Saturn with a diameter of 5800 Km was
discovered in 1655 by Christiaan Huygens who
realized that Saturn is in fact surrounded by a
bright ring, the large ring of Saturn. |

In Roman mythology
Saturn is the god of agriculture. The associated Greek god, Cronus, was the
son of Uranus and Gaia and the father of Zeus.

Saturn has the
lowest density of any planet in our solar system and would
actually float if it was placed in water!
