FURTHER EVIDENCE FOR IMPACTS IN THE OUTER SOLAR SYSTEM

• ORBITS/ROTATION:

  • URANUS: rotates on its side, with all of its moons/rings (98 degree tilt relative to orbit)
  • NEPTUNE: 2 moons have odd orbits
    • Moon Nereid has a large elliptical orbit
    • Moon Triton orbits backwards
  • PLUTO/CHARON: elliptical and tilted orbit about the Sun
