Basic Facts

• Equatorial diameter 120,536 km
• Mass 95 times that of Earth and 30 of Jupiters
  mass
• Surface Gravity 0.74 of Earth
• A day on lasts slightly less than 1/2 of a day on
  Earth
• You would have to be older than 29 to have spent
  1 year on Saturn

3
Characteristics

• Density lowest in the Solar System
• Average Temperature -285 F
• Distance from Sun 9.5 AU
• How does this distance compare to Earth?
• Can we stand on Saturn?

4
Interesting Features

• Does Saturn have a magnetic field?
• No volcanoes or mountains are present.
• Hurricanes?

5
Saturns Interior

• Little is known about the core of Saturn due to
  the thick atmosphere
• Core is projected to be composed of a mix solid
  materials (rocks) and ice
• The surface of the core should be covered in a
  layer of liquid hydrogen

6
Saturns Atmosphere

• The atmosphere is composed of 93 H2, and trace
  other gases
• Atmospheric convection produces heat, and causes
  the bands of color
• The color of the surface is caused by
  ammonia(NH3) in the atmosphere

7
Saturns Rings

• Discovered by Galileo Galilei in 1610
• Consist of 7 divisions
• Span up to 282,000 km (3/4 of the distance
  between Earth its moon)
• Made up of hundreds of thousands of ice particles

8
7 Divisions of Rings

• Named after alphabet letters, alphabetical from
  discovery
• From outermost ring, they are D, C, B, A, F, G
  and E
• A, B, and C rings are largely visible while rings
  F and G are very thin and harder to see

9
Ring Gaps

• Gap between A and B ring called Cassini Gap
• Gap between A and F rings called Encke Gap

10
Theories of Formation of Rings

• Still not exactly sure how rings came into
  existence
• A couple theories based on photographs taken from
  Voyager and Cassini missions
• Rings are young, therefore, shattered meteorites
  believed to be cause of rings

11
Saturn Ring Spokes

• Dark spots up to 20,000 km on B ring
• Rotate at same rate as Saturns magnetic field
• Different theories for existence

12
Roche Limit

• The distance within which a celestial body held
  together only by its own gravity will
  disintegrate due to a second celestial body's
  tidal forces exceeding the first body's
  gravitational self-attraction

13
Four missions

• Pioneer 11
• Voyager 1
• Voyager 2
• Cassini
• (2004-current)
