Jupiter
.


Jupiter is the fifth and largest planet in our solar system. This gas
giant has a thick atmosphere and a dark, barely-visible ring
composed of dust from nearby meteoroids. Its most prominent
features are bands across its latitudes and a great red spot (which is
a storm).
Jupiter is a gaseous planet; it does not have a solid surface like the
Earth does (but probably has a solid, rocky core 10 to 15 times the
mass of the Earth). When we look at Jupiter, we are seeing icy
clouds of gases moving at high speeds in the atmosphere. The
surface temperature of the highest clouds is approximately -153°C.
Jupiter's atmosphere is composed of about 90% hydrogen and 10 %
helium.


Jupiter has four large moons and dozens of smaller ones
(there are about 60 known moons so far). Galileo first
discovered the four largest moons of Jupiter, Io, Europa,
Ganymede, and Callisto in 1610.

Saturn

Saturn is the sixth planet from the sun in our solar system. It
is the second-largest planet in our solar system .

Each day on Saturn takes 10.2 Earth hours. A year on Saturn
takes 29.46 Earth years; it takes 29.46 Earth years for Saturn
to orbit the sun once.

Saturn has dozens of moons (33 discovered as of August,
2004). It has 18 named moons. including Titan (the largest),
Rhea, Iapetus, Dione, Tethys, Enceladus, Mimas, Hyperion,
Phoebe, Janus, Epimetheus, Pandora, Prometheus, Helene,
Telesto, Atlas, Calypso, and Pan (the smallest named moon
of Saturn). At least a dozen others have been noted (but not
named
yet).

Saturn's bright rings are made of ice chunks (and some
rocks) that range in size from the size of a fingernail to
the size of a car. Although the rings are extremely wide
(almost 185,000 miles = 300,000 km in diameter), they
are very thin (about 0.6 miles = 1 km thick).

Uranus


Uranus is the seventh planet from the sun in our solar system. This
huge, icy planet is covered with clouds and is encircled by a belt of
11 rings and 22 known moons. Uranus' blue color is caused by the
methane gas in its atmosphere.
Uranus is tilted on its axis at an angle of 97.9%. It rotates from top to
bottom instead of side to side like other planets. Astronomers
believe that Uranus was hit by another object that knocked it on its
side, billions of years ago.

Uranus is a frozen, gaseous planet with a molten
core. Uranus' atmosphere consists of 83%
hydrogen, 15% helium and 2% methane.


Neptune is the eighth planet from the sun
in our solar system. This giant, frigid
planet has a hazy atmosphere and strong
winds. This gas giant is orbited by eight
moons and narrow rings arranged in
clumps. Neptune’s color is caused by
methane gas in its atmosphere. Average
temperature is -225 C

Astronomers have discovered eight moons revolving around
Neptune. Neptune’s largest moon is named Triton. Triton’s
south pole is covered with ice and dark material erupts from
underneath of it.

Pluto


Pluto is a dwarf planet that usually orbits past the orbit of
Neptune. It was classified as a dwarf planet in 2006; before
that it was considered to be a planet, the smallest planet in
our solar system. Pluto is smaller than a lot of the other
planets' moons, including our moon. Pluto is the only
"planet" in our solar system that has not been visited by
our spacecraft yet. We only have blurry pictures of its
surface; even the Hubble Space Telescope orbiting the
Earth can only get grainy photos because Pluto is so far
from us. In 2015, a spacecraft called New Horizons
(launched by NASA in 2006) will visit Pluto.
