In Roman mythology, Jupiter (also
known as Jove; Greek Zeus) was the king of Heaven, and Earth, and of
all the Olympian gods. Jupiter later was named king during a special
meeting after overthrowing Saturn. This is very appropriate due to
Jupiter's dynamic atmospheric motion, but also the fluctuating cloud
patterns chased by storms not to mention the stunning brightness
(fourth only to the sun, moon, and Venus). It is apparent that
Jupiter was also quite the ladies man resulting in his wife Hera's
maddening jealousy.
Jupiter is the fifth planet from the sun, and uncomparably the
largest. It is 483 million miles from the sun. In diameter Jupiter
measures 88,736 miles and its over all mass is about 318 times the
Earth's. Jupiters rotates every 9 hours and 55 minutes, and one
revolution takes place about every 12 Earth years.
Jupiter's atmosphere is about 90% hydrogen and 10% helium. There are
a few traces of ammonia, methane, water, and it is possible sulfur
giving Jupiter its amazing appearance. When we look at gaseous
planets such as Jupiter we are actually looking at the top clouds in
the atmosphere. Gaseous planets do not have solid surfaces like the
Earth. The gases get denser to the core, but never solid. It is
considered to have a relatively small atmosphere layer compared to
the interior of the planet.
Jupiter is most commonly known for the Great Red Spot. The red spot
is 12,000by 25,000 kilometers (could hold two Earths). It has been
proven that the Great Red Spot is a high pressured storm where clouds
are higher and colder. The Great Red Spot has been observed for over
300 years. How it can persist for so long is still unknown.
Jupiter
has 16 known moons. Io has active volcanism and Europa contains a
possibility of a water environment. The moons or satellites
were
named by the figures is Zeus life, mostly his lovers. Jupiter also
has rings resembling Saturn, only much darker and smaller.
At the start of November Jupiter continues to emerge into the evening
sky to the east. It is still one of the brightest and most visible.
The most exciting occurrence to the naked-eye is Jupiter approaches
Saturn in a western motion. They will reach minimum separation
during twilight in late May. During the late fall and winter months
you could watch the full rotation of Jupiter.
