NASA Saturn Image     Saturn is almost twice as far from the Sun
as Jupiter at nearly 900 million miles.  It is second in size in
our solar system, surpassed only by Jupiter, but Saturn's mass
is much smaller. Saturn's specific gravity is less than water's,
meaning it would float on a body of water!  Like Jupiter, Saturn
rotates extremely fast, and completes a rotation in about 10
hours.  It takes a little over 29 years to make one revolution
around the Sun.  Saturn has 60 confirmed satellites, many of
which are buried inside Saturn's smaller ring systems which are
being discovered by NASA's Cassini spacecraft.  It is very
difficult for astronomers to count the number of moons revolving
around Saturn, because it is difficult to distinguish between
tiny moons and the numerous ice chunks composing Saturn's
smaller ringlets.  The large moon Titan is the most interesting
in terms of atmospheric composition (mentioned below).  It is
likely more satellites will be found in the future when
astronomers diagnose Satur
