JUPITER

GENERAL FACTS

• Largest planet in our Solar System
• 5th planet from the sun (778,412,020 km away)
• 10 orbital period
• Slow speed, orbits sun in 12 years
• A gas giant

GENERAL FACTS (CONT.)

• When an object (like the probe) enters its atmosphere,
• the frictional forces on the heat shield raises the temp
• to 2x hot as the surface of the sun

DISCOVERY

• Name: Zeus, came from Greek mythology
• Overthrew father (Saturn)
• Split universe with Neptune & Pluto
• 1610, Galileo saw 4 large moons (Galilean moons)
• He saw: Io, Castillo, Europa, Ganymede

STRUCTURE/FEATURES

• Under atmosphere, there is an ocean
• The ocean is made up of H2O
• There is nothing in between the ocean and the atmosphere
• 1,300 earths fit in Jupiter
• High amounts of radiation in the rings and some of its moons

STRUCTURE/FEATURES (CONT.)

• Atmosphere: mostly hydrogen and helium
• 50 known moons, 13-17 pending confirmation
• Faint rings (about 3). Gossamer, Main, Halo
• Rings can only be seen when passed in front of the sun
• Lots of storms, lots of colors. Causes Jupiter to appear different colors

STRUCTURE/FEATURES (CONT.)

• Tilt of axis: only 3 degrees
• Surface temp: -145 degrees C
• Core temp: 24,00 degrees F
• Jupiter gets about 1/25 sunlight vs. Earth

GREAT RED SPOT/EYE OF JUPITER

• The Great Red Spot is a giant storm
• Has lasted for hundreds of years
• Larger than earth
• Fades & brightens due to the intensity
• Seen by Galileo

PROBES

• Pioneer 10- first mission to Jupiter
• Pioneer 11- studied environment around Jupiter/Saturn
• Voyager 1- sudied outer solar system
• Voyager 2- studied interstellar space
• Galileo Spacecraft (p&o)-to see under the clouds

CHARACTERISTICS

• If 100x more mass, it is beleived
• that it could be a star
• Interior: rock, metal, hydrogen compounds
• About 7% wider at equater
• Looks like marble: storms/colors/solar activity

COOL FACTS

• Has stopped several astroids from hitting earth
• Auroras, just like earth, but only blue
• The shock of the atmosphere deflects solar wind
• Auroras are caused by electrically charged particles
• Unknown source but thought to come from innermost satellites
