Study Notes
Jupiter's Interior
- Terrestrial planets formed within the frost line
- Heavy materials sink to Jupiter's core; the rest is gases and ice
- Pressure increases as you move deeper into the atmosphere, becoming stronger and stronger
- Gases are squeezed tightly and become metallic hydrogen, forming liquid and solid hydrogen
Juno Space Probe
- Orbits Jupiter to study its effects on its orbit
- Used to determine the distribution of mass in Jupiter
Jupiter's Core
- A medium-sized planet smashed into Jupiter, causing a disruption of the core
- The core was broken up and distributed throughout the planet
- Has not completely settled yet
Jupiter's Storms
- Complex clouds and stable storms; strong winds
- Storms are several thousand kilometers thick
- Bands (possibly) of storms persist for decades
- Bands are distributed within the depth of Jupiter's atmosphere
- Water clouds form white bands
- Different gases become liquids at different temperatures and pressures
- Ammonium hydrosulfide clouds form orange bands
Saturn
- Second largest planet, not heavy or condensed
- Mass is less than Jupiter's
- Huge hexagonal storm at its north pole
- Ice giant, with a small rocky core (possibly)
- Thick water, ammonia, and methane mantle
- Thick H2/He atmosphere
- Rotates at 98 degrees
- Has rings and many moons
Uranus
- Coldest planet
- Small rocky core (possibly)
- Thick water, ammonia, and methane mantle
- Thick H2/He atmosphere
- Rotates at 98 degrees
Neptune
- Furthest Jovian planet from the sun
- Similar to Uranus, with a 28-degree tilted rotation axises
- Strongest winds in the solar system
- More surface features than Uranus
Moons
- Io: Lots of volcanoes, no craters
- Europa: Ice structure, no craters
- Ganymede: Ice structure, some craters
- Callisto: Many craters
Most and Least Geologically Active Moons
- Io is the most geologically active
- Small objects cool quickly and are less likely to remain geologically active
- Europa has a large ocean beneath its surface
- Ganymede is slightly larger than Earth's moon; craters but less active compared to Io
