The outer planets
The outer planets
• The outer planets are the planets found after
the asteroid belt
• Not counting Pluto, the outer planets are
giant, gas or ice planets
• Pluto was demoted to a dwarf planet in 2006
Jupiter
• 5th planet from the sun
• 5.20 AU from sun
• 50 known, 17 waiting confirmation = 67 moons (63 in
book)
• 1 rotation is 10 hours
• Gas giant, no solid surface. Prediction of a solid inner
core about the size of Earth
• Giant red spot is a gigantic storm that has been going
on for more than 300 years
• Jupiter cannot support life but some of its moons can
• Atmosphere mostly of hydrogen and helium
Saturn
• 6th planet from the sun
• 9.58 AU from sun
• 53 known moons with 9 awaiting confirmation
(47 in book)
• 1 rotation is 10.7 hours
• Gas giant with no solid surface
• Has spectacular ring system, 7 rings total with
gaps in between
• 5 missions to Saturn, Cassini (2004) still exploring
Uranus
• 7th planet from the sun
• 19.19 AU from sun
• 27 moons named after Shakespeare and Alexander Pope
characters
• 1 rotation is 17 hours, retrograde rotation (like Venus)
• Ice giant, hot dense fluid of icy material (water, methane,
ammonia, with a small rocky core) and atmosphere of H,
He, methane.
• Has a faint rings, inner rings are narrow and dark, the outer
ones are brightly colored
• Voyager 2 is the only spacecraft to visit
• Rotates on its side (spins horizontally)
White dot is moon Ariel, black dot is the shadow.
Neptune
• 8th planet from sun
• 30.04 AU from sun
• 13 moons, 1 awaiting confirmation. Named after
various sea gods and nymphs in Greek myhtology
• 1 rotation is 16 hrs
• Sister ice giant to Uranus
• Has 6 rings
• Voyager 2 only mission to Neptune
• At times in its orbit, it is further then Pluto (1979
to 1999)
Dwarf Planets
• Dwarf planets do not clear the neighborhood
around its orbit
• Ceres: 1801, located 2.7 AU from sun, orbits
in about 4.6 years, located in the asteroid belt
• Pluto: 1930, located 39.2 AU from sun, orbits
lasts 248 years. Has 3 moons.
• Eris: 2006, elliptical orbit 38-98 AU from sun,
orbit takes 557 years. One moon, Dysnomia.
