Transcript The Solar System: JUPITER by - Etiwanda E

The Solar System:
Jupiter...
• is the 5th planet from
the sun
• is a gas giant
• has a diameter of
142,984 km (more than
300 times bigger than
Earth and more than
twice as big as all the
rest of the planets
added together)
• is 778,330,000 km
from the sun
• has 39 known
satellites
• Jupiter was named
for the Greek god
Zeus, who was the
ruler of Mount
Olympus and king
of the gods.
Galileo’s Discovery
Using a homemade telescope,
Galileo discovered 4 moons
revolving around Jupiter in
1610. These moons are known
as the Galilean moons: Io,
Ganymede, Callisto, and
Europa. This was important
evidence that the earth was
not the center of the solar
system.
Exploration of Jupiter
• Voyager 1
• Pioneer 10
– 1st spacecraft to pass
asteroid belt
– found intense radiation
around Jupiter
• Pioneer 11
– measured solar wind,
Jupiter’s magnetic field
and atmosphere
– investigated
atmospheres and moons
– found Jupiter;s rings
• Voyager 2
– found volcanoes on Io
– found frozen crust on
Europa
• Galileo
– 1st spacecraft to orbit
a gas planet
Jupiter -has a core of
rocky material
Above the core lies the
main bulk of the planet
in the form of liquid
metallic hydrogen
• Jupiter is about 90%
hydrogen and 10%
helium
• Three distinct layers
of clouds are believed
to exist: ammonia ice,
ammonium
hydrosulfide, and a
mixture of ice and
water.
• Jupiter has high
velocity winds
• The Great Red Spot
is an oval big enough to
hold two Earths.
Rotation/Revolution
Mean distance from the Sun: 5.203 AU
(778,400,000 km/483,700,000 mi)
Length of Year: 11.86 Earth years
Rotation Period: 9.92 hours
Mean Orbital Velocity: 13.06 km/s (8.1 mi/s)
Inclination of Axis: 3.12° Diameter: 142,980
km/88,700 mi
Satellites
Io is the
third largest
moon It has
active
volcanoes.
Ganymede is the
largest moon in
the solar system.
.
Europa is the
4th largest
moon and has a
smooth frozen
crust. There
may be liquid
water under it.
Callisto is the
second largest
moon and is
almost as big
as Mercury.
