Jupiter is the 5th planet from the sun
Its diameter is about 0.00089 AU from pole to pole and about 0.00095 AU at the equator making it the largest planet in our solar system
Average distance from the Sun is approximately 5.20 AU
Its rotational period is about 0.41354 days, while its orbital period is about 4332.71 days
Jupiter’s orbital eccentricity is 0.0483, which indicates its orbit is fairly elliptical
It has a mass of approximately 1.09 × 1027 kilograms, making it about 318 times as massive as Earth.
Jupiter has very few similarities to Earth, or any of the inner planets for that matter
It is very much like the other three gas planets: Saturn, Uranus and Neptune
The four gas giants are mainly composed of similar chemicals (Helium, Hydrogen)
They all possess rings of some sort
Neptune has a very similar “spot” just as Jupiter does
However, Jupiter is probably most like Saturn as they both have a metallic hydrogen layer
Jupiter was named after Jove, the chief god of Roman mythology. The Italian scientist, Galileo was the first astronomer to view Jupiter through a telescope. However, ancient Romans first wrote about Jupiter as early as the 17th century, and they named the planet after one of their gods.
In ancient Roman religion, Jupiter was the King of the gods. The name "Jupiter" means "the best and greatest" (OptimusMaximus). He is equivalent to the Greek God Zeus.
Jupiter was the spirit of the sky and worshiped as the god of thunder and lightning. During wartime he was sought to protect in battle and was the 'giver of victory.' During peacetime he was the god of justice and morality.
Galileo Galilei discovered the first four moons
The interior of Io (upper left) indicates a larger rock core, a mantle and crust. Europa (upper right) demonstrates an icy curst, a liquid ocean, a mantle and a smaller rocky core - possible metallic. Ganymede (lower left) is similar to Europa and may also posses a metallic core. Callisto (lower right) may have a core, but very small - the interior is thought to be water mixed with rock.
~ 71% Hydrogen
~ 24 % Helium
~ 5% Other
The chemical composition of Jupiter is almost identical to that of the Sun…
~ 70% Hydrogen
~ 28% Helium
~ 2% Other
The atmosphere of Jupiter consists of intense wind patterns, running horizontally across the planet
The surface is composed of mainly gases, with clouds of ammonia crystals
Jupiter experiences different climates, however they are much more extreme than what we have on Earth
It’s famous “Great Red Spot” is actually an ancient storm
Inside this storm is essentially a massive hurricane
The average surface temperature on Jupiter is between -110 and -220 degrees Celsius
A main ring - The brightest ring
A halo ring - The ring that look like a doughnut
Two gossamer rings (Amalthea and Thebe) - Very faint rings that overlap each other.
The composition of the rings came from the pictures by the Galileo spacecraft in 1996 and 1997. which showed that Jupiter’s rings are made of dust. (AstronomyOnline.org)
Great Red Spot is a continual anticyclonic storm. The storm alone is larger than the planet Earth, or Mercury. According to astronomers, there is evidence that the storm existed on the planet at least since 1831.
The first probe to visit Jupiter was the Pioneer 10.
The most remarkable Jupiter mission was the Galileo probe. Launched in October of 1989, this provided some of the best views of the moons of Jupiter
Prometheus One will study Jupiter in depth and will also orbit three of its moons: Callisto, Ganymede and Europa. Continual study of the presence of water will be performs. Launch is proposed for 2015.
Some of the clearest images of Jupiter came from the Cassini-Huygens probe
Scientists have speculated that
life on Jupiter is possible. This
would occur beneath the cloud
cover where room temperature
conditions exist, these life forms would
be airborne although this theory is
thought to be highly speculative.(Vic
Jupiter’s name implies that it is the “King of the Planets
The diameter of the Great Red Spot is about the same as three of Earth’s diameters
Jupiter is slowly shrinking
It is the faster spinning planet in our solar system (takes10 hours to complete full rotation on axis)
Jupiter’s clouds are about 50 km thick
Jupiter’s magnetic field is 14 times as strong as Earth
The Great Red Spot is about 300 years old
Jupiter is flattening due to rotational forces
Jupiter is about 2.5 times bigger than all the other planets combined
Some astronomers believe Jupiter was a failed star
Approximately 90% of the upper atmosphere is hydrogen, and approximately 10% of the upper atmosphere is helium.
