Discovery of Jupiter
• No one can definitely say who discovered Jupiter
as it is one of the 5 planets you can see in the night
sky.
• It was called Marduk in Babylonian, Zeus in Greek,
and Jupiter in the Roman times.

Structure
• Jupiter has a low density meaning it is mostly gas.
• Jupiter emits twice as much energy as the sun gives
off.
• Inside is very hot and dense.
Moons
• In 1610 Galileo Galilei discovered Jupiter has 4 large
moons rotating it, that being: Europa, Io,
Ganyemade, and Callisto.
• Referred to as Galileo's satellites.

Io
•
Most volcanically active body in the solar system. Because of
Jupiter’s immense gravity it causes tides into Io’s solid surface.
• Closest to Jupiter.
• Orbit resonance is 4:1 to Ganyemade and 2:1 to Europa.
Meaning it makes 2 orbits by the time Europa does one and
Ganyemade does 2.
• Io is 5% greater radius than our moon, and 21% greater mass.
• Extremely thin atmosphere which is mainly made of sulfur
dioxide.
Europa
• Slightly smaller than our moon
• Primarily made of silica and probably has an iron
core, surface Is composed of ice.
• Under ice is an ocean with possible life
• Only Fly-By missions has been enacted
• Radius or 670k meters
• Spins Faster than it orbits
Callisto
• Discovered by Galileo on January 7th, 1610
• Callisto is the third largest moon in the galaxy
o It is almost the size of Mercury
• Is the outermost of the Galilean satellites
o Orbits beyond Jupiter’s main radiation belts
• Has the darkest Galilean surface
o But is twice as bright as our moon
• It has the oldest landscape in the solar system
• It is the most heavily cratered object in the solar
system
Ganyemade
• Ganyemade is the largest moon in the solar system.
• It has a diameter of 5,268 km (3,273 mi), 8% larger
than that of the planet Mercury, but has only 45% of
the latter’s mass.
• Ganymede is the only moon in the Solar System
known to possess a magnetosphere, likely created
through convection within the liquid iron core.
• Discovered January 7, 1610
Atmosphere
• Jupiter has no boundary between its atmosphere
and the rest of the planet
• Has four atmospheric levels
o Troposphere, Stratosphere, Thermosphere, and
Exosphere
• Each oval spot is a storm
• The darker ones are lower warmer storms
• The lighter ones are higher more cool storms
• Jupiter's Atmosphere Has Weird Hot Flashes |

Explorations
• First automated spacecraft sent to Jupiter’s system
was Pioneer 10 in 1973
• Jupiter is the most visited of our solar systems outer
planets
• Manned missions aren't feasible with current
technology
• 7 automated probe flybys
• Voyager one animation

Possibilities of Life
• The planet is a gas giant composed mainly of hydrogen and
helium. There is virtually no water to support known life forms.
The planet does not have a solid surface for life to develop
anywhere except as a floating microscopic organism.
• Free floating organisms could only exist at the very tops of the
clouds due to atmospheric pressure that is progressively more
intense than anything seen on Earth.
•
Jupiter is completely inhospitable to life as we understand it
