Astronomy

Two ways planets move

1) rotate

2) revolve


Inner planets mercury venus earth mars

INNER PLANETSMercury, Venus, Earth, Mars

  • SURFACE: rocky, terrestrial

  • MOONS: few or none

  • RINGS: none

  • ORBITS: faster than outer planets

  • ROTATIONS: slower than outer planets


Outer planets jupiter saturn uranus neptune

OUTER PLANETSJupiter, Saturn, Uranus, Neptune

  • SURFACE: mostly gas; “gas giants”

  • MOONS: many

  • RINGS: many

  • ORBITS: longer than inner planets

  • ROTATIONS: faster than inner planets
