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 surfaceo 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 | Spa

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 http://www.cleanvideosearch.com/media/action/yt/watch?videoId=KG5KctTOkEk

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
