Our Introduction
In our solar system, nine planets circle around our Sun. The Sun sits in
the middle while the planets travel in circular paths (called orbits)
around it. These nine planets travel in the same direction (counterclockwise looking down from the Sun's north pole). The picture on the
right shows the different paths and
positions of each planet.
About Our Solar System





There are nine planets in our solar system
Mercury,Jupiter,Venus,Saturn,Earth,Uranus,Mars,Neptune and Pluto.
The solar system is made up of two parts:
The inner solar system contains Mercury,Venus,Earth and Mars.
The outer solar system contains Jupiter,Saturn,Uranus,Neptune and
Pluto

Scientists say that nine planets are changed into eight planets because
Pluto is not a planet anymore. Scientists are still unsure as to exactly
what it’s made of.

Sometimes you can see the nine(eight)planets in the sky at night. Some
is by using the telescope and some not.
The brightest planet is Venus with an apparent magnitude of-4.6.

About Jupiter

Jupiter does not have a solid surface due to its gaseous composition. The swirls and
bands we see when looking at Jupiter are the tops of clouds high in its atmosphere.
Jupiter has high speed winds that whip by at more than 400 mph!
These winds are trapped in the planet's wide bands of latitude.
Each band has a slightly different chemical make-up and
temperature from the others.
This gives it a color which is different from surrounding bands.
The light colored bands are called "zones." The dark colored bands
are called "belts."
The vivid colors seen in Jupiter's clouds are probably the result of subtle
chemical reactions in Jupiter's atmosphere.
The clouds are a different color, depending on its altitude.
Blue clouds are lowest, followed by brown and white clouds.
Red clouds are the highest.
Sometimes we see the lower cloud layers through holes in the upper cloud
layers.
About Jupiter Part 2




Jupiter's most outstanding and interesting feature is called "The Great
Red Spot."
The Great Red Spot is an oval about 12,000 km by 25,000 km - big
enough to hold two Earths!
Jupiter also has other smaller similar spots.
The Great Red Spot is a high-pressure region whose cloud tops are
much higher and colder than the surrounding areas.

Jupiter has faint rings like Saturn’s, but much smaller. Unlike Saturn’s,
Jupiter’s rings are dark.

They’re probably composed of very small grains of rocky material.
The visible surface of Jupiter is a deck of clouds of ammonia crystals, the
tops of which occur at a level where the pressure is about half that at
Earth’s surface.

When It’s Evening




Why don’t you try to look for Jupiter at the
evening.
When it is in the nighttime sky, Jupiter is often
the brightest “star” in the sky (it second only
to Venus, which is seldom visivle in the dark
sky).
The four large Galilean moons are easily
visible with a pair of binoculars.
You can even see a few of Jupiter’s bands
and the Great Red Spots with a small
astronomical telescope.
About Jupiter Part 3



Jupiter is the largest of the nine planets, more than 10 times the diameter
of Earth and more than 300 times its mass. In fact, the mass of Jupiter is
almost 2.5 times that of all the other planets combined.
Being composed largely of the light elements hydrogen and helium, its
mean density is only 1.314 times that of water. The mean density of
Earth is 5.245 times that of water.
The pull of gravity on Jupiter at the top of the clouds at the equator is 2.4
times as great as gravity's pull at the surface of Earth at the equator. The
bulk of Jupiter rotates once in 9 hours, 55.5 minutes, although the period
determined by watching cloud features differs by up to five minutes due
to intrinsic cloud motions.
About Jupiter Part 4


The meteorology of Jupiter is very complex and not well understood.
Even in small telescopes, a series of parallel light bands called zones and
darker bands called belts is quite obvious. The polar regions of the planet are
dark. Also present are light and dark ovals, the most famous of this being The
Great Red Spot.
The innermost of the four large satellites of Jupiter,Io, has numerous large
volcanoes that emit sulfur and sulfur dioxide.
The two Voyager spacecraft discovered that Jupiter has faint dust rings
extending out to about 53,000 kilometers (33,000 miles) above the atmosphere.
The brightest ring is the outermost, having only 800-kilometre (500 mile) width.
Next inside comes a fainter ring about 5,000 kilometres(3,100 miles) wide while
very tenuous dust extends down to the atmosphere.
Facts About Jupiter
~Jupiter is a giant gas planet which is made up of about 90% hydrogen and 10% helium.
~Jupiter was first visited by the Pioneer 10 spacecraft in 1973. It was later visited by Pioneer
11, Voyager 1, Voyager 2 and Ulysses. The spacecraft Galileo is currently in orbit around
Jupiter and will be sending back data for at least the next two years.
~Jupiter is so big that you could cram 1,000 Earths inside of it! That's *mighty big*!
~It is thought that Jupiter's "Great Red Spot" is a storm of swirling gas that has lasted for
hundreds of years. Scientists are still unsure as to how such a storm could last for so
long.
~Jupiter has 16 known moons! There are four large "Galilean" moons, and 12 small ones.
This is the symbol for Jupiter:
Jupiter is the fifth planet from the Sun and by far the
largest of all nine planets.
Jupiter is more than twice as massive as all the other
planets combined - It's 318 times bigger than the Earth!
Jupiter is a big planet.
Jupiter is a gas planet.
