  1. Characteristics of Outer Planets By: Holly Fowle

  2. Jupiter

  3. Jupiter • Jupiter is the fifth planet from the Sun. • It takes 11.9 Earth years just to complete one full orbit. • It is the biggest planet in the solar system, with twice the mass as all of the other planets combined!

  4. Jupiter’s atmosphere • Jupiter has a very gaseous surface. • It contains alternating light- and dark-colored bands. • The dark bands are areas of sinking gas and light bands are areas of rising gas.

  5. Jupiter’s Winds • Jupiter’s winds blow parallel to its equator • Winds at the equator move east at the average speed of 400 kilometers per hour. • Winds traveling north and south move at 100 kilometers per hour.

  6. Great Red Spot • Jupiter’s “Great Red Spot” is the most striking feature on Jupiter’s surface. • It rises 8 kilometers above its clouds. • It is just one of Jupiter’s several different spot.

  7. Jupiter’s Magnetic Field • Jupiter has the strongest known magnetic field. • The interaction between solar wind and the magnetic field cause Jupiter to have auroras. • It also has intense lightning storms

  8. Jupiter’s Radiation • Jupiter radiates between 1.5 and 2.0 times as much heat back into space as it obtains from the sun. • The extra heat is thought to come from Jupiter’s original heat of formation and from contraction due to its gravity.

  9. Saturn

  10. Saturn • Saturn is the sixth planet from the sun. • It takes nearly 30 Earth years to complete one full orbit. • It turns on its axis once every 10.7 Earth hours.

  11. Saturn’s bands • Saturn has colored bands like Jupiter, which are different areas of rising and sinking air. • Saturn has fewer bands than Jupiter and its wind speed is faster: about 1800 km. per hour. • Saturn’s density is low like Jupiter’s – less than 1 gram per cubic centimeter.

  12. Saturn’s Radiation • Saturn radiates between 1.5 and 2.5 times as much energy as it receives from the sun. • Similar to Jupiter, it obtains sources of internal heat. • It has a weak magnetic field.

  13. Uranus

  14. Uranus • Uranus is the seventh planet from the sun. • It takes 84 Earthly years to complete one full orbit. • It turns on its axis once every 17.2 hours! • Its axis of rotation is very unusual; Uranus is tipped almost completely over!

  15. Uranus’s Magnetic Field • Uranus’s magnetic field is produced at its core, which rotates at the same rate as the planet itself. • The spiral pattern traced by the magnetic field made it possible to figure out Uranus’s rate of rotation precisely.

  16. Uranus’s Temperature • Uranus’s temperature is very strange. • The side of Uranus facing the sun is not hotter than the side not facing the sun; they are the same temperature.

  17. Neptune

  18. Neptune • Neptune is the eighth planet from the sun. • It was discovered in 1846. • It takes 16.1 Earth years to complete one full orbit

  19. Neptune’s magnetic field is tipped 47 degrees. • Its wind speeds up to 2200 kilometers per hour. • Neptune gives off 2.7 times more energy than it obtains from the sun. • Its temperature was once measured at –214oC.

  20. Pluto

  21. Pluto is the coldest, smallest, and most distant known planet in our solar system. • It was discovered in 1930. • Its surface temperature is below –220oC.

  22. Pluto’s Atmosphere • Most of its atmosphere of helium and methane is frozen to its surface. • That’s why Pluto seems to be made of just water, ice, and rocks.

  23. Pluto takes 248 Earth years to complete an orbit. • At one point, Pluto’s orbit comes closer to the sun than Neptune’s.

  24. Pluto Now • Right now, though, Neptune is closer to the sun than Pluto. • Pluto was closer to the sun between the years 1969 and 1999.
