  4. Saturn possesses about ________ the mass of Jupiter.
  5. Saturn's oblate shape is a result of ________.

    Axis of rotation tilted 97 degrees
  9. Uranus was discovered by William Herschel in 1781, but had unknowingly been seen much earlier by _________.
  10. Uranus' tropical and sidereal orbit periods are different values from one another. That means that ________.
    The Axis of Rotation is precessing
  11. Neptune's largest moon, Triton is odd in the sense that _________.
    Its orbital direction is retrograde
  12. In relation to the sun, Uranus and Neptune formed ________.
    Closer in and then drifted outward, scattering the icy planetisimals of the outer accretion disk inwards
  13. Uranus and Neptune appear to have a blue or blue-green color, primarily due to the amount of _______ in their atmospheres
  14. Both Uranus and Neptune have weak magnetic fields for their size, but the real oddity is that ________.
    The Axis of the magnetic fields are both tilted relative to the rotation axis and offset from the center of the planet
  15. Neptune's Tropical orbital period is less than its sidereal orbital period. This means that _________.
