1. The outer planets

2. 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

3. Jupiter 5 th 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

5. Saturn 6 th 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

7. Uranus 7 th 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)

8. White dot is moon Ariel, black dot is the shadow.

9. Neptune 8 th 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)

11. 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.

13. Calculate your age Outer planetsYour age times 365 Approximate length of year Divide the numbers Jupiter EX: 28 x 365 = 10220 4344 E.days (12 yrs) EX: 2.4 yrs old! Saturn EX: 10220 10767.5 days (29.5yrs) Uranus EX: 10220 30660 days (84 yrs) Neptune EX: 10220 60225 days (165 yrs) Pluto EX: 10220 90520 days (248 yrs)
