|
Liquid Metallic Hydrogen
|
Causes Electrical Current and Magnetic Field found in Jupiter and Saturn
|
|
|
Roche Limit
|
distance from a planet within which a moons own gravity cannot hold it together. Large moons are held together with their own gravity.
|
|
|
Ring System
|
Made of bright ice chunks
Particles are dark and reddish Not icy, yes rocky |
|
|
Surface Features- Jupiter
|
Most massive of all Jovian Planets
Mostly liquid hydrogen Magnetic field is 10 times that of Earths |
|
|
Jovian Planets
|
outer 4 planets
Jupiter, Saturn, Uranus, Neptune All large, low-density worlds w/thick atmosphere |
|
|
Ring System
|
Made of bright ice chunks
Particles are dark and reddish Not icy, yes rocky |
|
|
All 4 moons of Jupiter
|
Europa, Ganymede, Callisto, IO
|
|
|
Io
|
Youngest, still has active volcanoes
|
|
|
Europa
|
Frozen Moon, surface ice, maybe ocean underneath
|
|
|
Callisto and Ganymede
|
Almost Identical. Half Rock/Half ice
Ganymede-largest moon in solar system |
|
|
Saturn
|
Known for its ring system
|
|
|
Saturn's Moons
|
Titan- nitrogen atmosphere.
|
|
|
Saturn's Rings
|
a-golf balls size chunks of ice
b-golf ball size chunks of ice c-bolder size chunks of ice (less than half as bright as a & b) contain less ice and more minerals (very dark) |
|
|
Uranus
|
1st newly discovered planet in 2000 years (1977)
|
|
|
Uranus' Moon
|
Miranda- innermost moon
14% diameter of Earths Moon Surface is marked by oval patterns called ovoids( oval patterns of grooves) |
|
|
Does Uranus have an internal energy source
|
No
|
|
|
Neptune
|
Great dark spot
Highly magnetic field- astronomers think that ammonia dissolved in the liquid water mantle and the mantle makes a good electric conductor. |
|
|
Neptune's Moon
|
Triton
|
|
|
Triton (Neptunes moon)
|
Has atmosphere of nitrogen and methane
really cold (significantly ice, some deposits of nitrogen frost are visible at southern pole. Active past |
|
|
History of Neptune
|
In 1989 Voyager 2 discovered Great Dark Spot (largest feature) Hubble's photos now show that the dark spot is gone.
|
|
|
Pluto
|
not really a planet
|
|
|
Pluto's Moon
|
Charon
|
|
|
Charon (Pluto's moon)
|
Discovered in 1978. (A lot like a comet) M
|
|
|
Meteorites Can be divided into 3 broad categories
Iron |
Solid chunks of iron and nickel (very heavy)
(dark irregular surface) |
|
|
Meteorites Can be divided into 3 broad categories
Stony |
silicate masses that resemble Earths Rocks
Tend to have a fusion crust caused by a melting in Earths Atmosphere |
|
|
Meteorites Can be divided into 3 broad categories
Stony Iron |
mixtures of iron and stone
|
|
|
Pluto
|
Discovered in 1930 by Clyde Tombaugh.
|
|
|
Neptune
|
Moon- Tryton
|
|
|
Jupiter
|
Has a heavy core of heavy elements and a deep mantle of liquid metallic hydrogen--how the magnetic field is generated
The magnetic field around Jupiter traps high energy particles from the sun to form intense radiation belts |
|
|
The Great Red Spot
|
Jupiter
It is a circulating weather pattern |
|
|
Moons on Jupiter
|
none are active
|
