Explanation:
Saturn is the second largest planet in our
Solar System. Saturn has been
easily visible
in the sky since history has been recorded.
Galileo used one of the
first telescopes in 1610 to discover Saturn's rings,
which he first thought were moons.
Maxwell showed in 1856 that
Saturn's rings couldn't be a single solid,
since Saturn's own gravity would break it up.
Were
Saturn's rings assembled into a single body,
it would measure less than 100 kilometers across.
The origin of
Saturn's rings,
and of unusual radial patterns that appear on them called
spokes, are still unknown. The
above representative-color picture
was taken from Earth in infrared light. A robot spacecraft
Cassini
launched in 1997 will reach
Saturn in 2004.
