Outer planet Atmospheres Flashcards
Jupiter
-5.2 AU from the sun
-radius: 73000 km (11x the earth)
-mass: 318 x the earth
density of Jupiter
-1.3 (water is 1)
-made of H and He
Jupiter’s atmosphere
-made up of H and he gas
-temperature of -200F
-filled with storms
Jupiter’s Mantle
-made up of liquid H and He
-no surface on planet (atmosphere blends into mantle)
Jupiter’s lower mantle
-made of metallic liquid H and He
Jupiter’s core
-made of rock, metal, and ice
Jupiter’s temperature
-35 degrees too warm
-radiates 2x the heat it gains from the sun due to energy from its creation
Jupiter’s clouds
-stacked in icy decks
-spread out in belts and zones (updrafts in zones and downdrafts in belts)
-blown about by zonal winds (eastbound in zones and westbound in belts)
Zonal wind patterns
-high and low pressures spread around by planets rotation
or
-the ends of fluid cylinders inside the planet
Jupiter’s storms
-great red spot is the biggest
Jupiter’s magnetic field
-19000 x stronger than the earth
-extends 2 mill. km
-has one due to liquid metallic H
-charged particles fill magnetosphere
magnetosphere
-region around a planet that is dominated by its magnetic field
Saturn
-Mass: 95x earth
-density: 0.7 (made of H and He)
Saturn is like Jupiter except…
-less He in atmosphere
-colors more mutes due to more haze
-less turbulence
-bands lessen at poles
-winds of 1000 mph
Uranus
-19 Au from sun
-radius: 25000km (4x earth)
-mass: 14 x earth
-density: 1.2 (made of water and rock)
-tipped 98 degrees so has extreme seasons
