<p ><b class="first" >T</b>he fifth planet orbiting the sun at a distance 5.2
|
||||
times the distance of Earth to the Sun, Jupiter forms a planetary system within
|
||||
itself. Scientifically believed to have almost evolved into a star, Jupiter
|
||||
still holds nuclear processes within, proving indications that Jupiter is a true
|
||||
planet.</p>
|
||||
|
||||
<p >With a rotation speed of 90,000 km/hr, Jupiter rotates around its axis in
|
||||
only 9 hours and 50 Earth minutes. Spinning at such an incredible pace, Jupiter
|
||||
forms visible dark and light belts of clouds.</p>
|
||||
|
||||
<p >Underneath these clouds, exists no physical surface without a true solid
|
||||
body-only liquid and breaks of solidity. The majority of Jupiter is composed of
|
||||
liquid hydrogen and helium that form a swirling of the phases of matter at a
|
||||
temperature of 30000 degrees Celcius at a pressure 30 million times that of
|
||||
Earth.</p>
|
||||
|
||||
<p >An example of Jupiter's surface structure is the Great Red Spot. Existing for
|
||||
at least 3 centuries, the Red Spot swirls as a gigantic oval in Jupiter's
|
||||
southern hemisphere. Rotating within itself, the Great Red Spot, swirls with a
|
||||
size greater than Earth every 12 days.</p>
|
||||
|
||||
<p >Phenomenally, Jupiter liquid core shrinks at a rate of 1mm per year.</p>
|
||||
|
||||
<p >Jupiter's own system of satellites, currently are numbered to contain 14.
|
||||
Jupiter's personal solar system grew from dust particles that formed near the
|
||||
Sun and others from the close asteroid belt, which got drawn to the giant planet
|
||||
by gravity.</p>
|
||||
|
||||
<p >The inner five: Amalthea, Io, Europa, Ganymede, and Callisto are bright stars
|
||||
on Earth's horizon and are of the most value to space exploration.</p>

|

<td >Approximately 3640km in diameter, the satellite is slightly larger

than our Moon. Active volcanoes eject sulfurous fumes. As Io orbits
|

Jupiter, it carries round with it a cloud of gas that simulates a

primitive atmosphere.</td>

known to possess an atmosphere. Its surface appears to be completely by

water ice with possible indications of life from the Jet Propulsion

Laboratory's Galileo mission.</td>
