What is the name of the satellite that orbits Jupiter at high speeds but does not leave its orbit because of the planet's pull? |
Io (thats io). |
|
|
What is the name of the swirling vortex of clouds, that are even larger than Earth, which have been raging for 300 years with no sign of abating? |
Great Red Spot |
|
|
Name and describe Jupiter's four most important satellites. What are all four called together? |
1. Io is the most volcanically active body in the Solar System 2. Europa has a significant liquid water ocean underneath its icy surface. Influenced greatly by tidal heating. 3. Ganymede seems to have a slushy water ocean underneath its icy surface 4. Callisto seems to have never chemically differentiated. -Galilean satellites |
|
|
Name and describe the missions to Jupiter. |
1. Pioneer 10 has left the solar system 2. Pioneer 11 has left the solar system 3. Voyagers 1 & 2 4. Galileo was the first craft to orbit Jupiter. After 14 years of flight time, and 8 years collecting data. Galileo was deliberately destroyed to prevent it from contaminating Europa's ocean. It was sent crashing into Jupiter's crushing atmosphere at 50 km/s. 5. New Horizons 6. Juno |
|
|
Describe Jupiter's orbit and rotation. |
-Obliquity of 3 degrees - Slightly oblate (enlarged at equator) -Rotates super fast |
|
|
Jupiter emits about _ times as much energy it receives from the _. |
1.7 and Sun |
|
|
Does Jupiter have a magnetic field? |
Yes, but we don't know how it's generated. |
|
|
Describe how we gathered information about Jupiter's atmosphere and what we discovered. |
- Galileo contained an ASI (atmosphere structure instrument) that it dropped into Jupiter's atmosphere. - Found that the clouds on Jupiter can be organized into dark belts (regions of descending gas) and bright zones (regions of rising gas) |
|
|
Name and describe the classification of satellites. |
1. Regular satellites orbit their planet closely and on the same equatorial plane. They are thought to have formed from the same nebula of gas and dust that formed the planet. 2. Irregular satellites are of unknown origin but are thought to have been captured by the. 3. Trojan satellites orbit the sun but are gravitationally bound to Jupiter i.e. they don't orbit Jupiter, they share its orbit. |
|
|
Name Earth's trojans. |
True Trojan: 2010 TH7 Enhanced: 2002 AA29 |
|
|
What principles did the Galilean satellites teach us? |
1. A planetary body's composition is dependent on the temperature of its materials. 2. Cratering can tell us the age of a hard surface 3. Internal heat has a large influence on the geology of a large satellites/planets. |
|
|
Describe Ganymede. |
-internal temperature is very hot (1500-1700 K) -has a very thin atmosphere! |
|
|
Describe orbital resonance. |
A gravitational phenomenon in which multiple bodies orbiting a single body follow an orbital pattern. i.e. in the time it takes Ganymede to orbit Jupiter once, Europa orbits twice, and Io four times. |
