Orbit definitions - One possible scheme

All six diagrams show the Sun in the middle (the orange dot) and a putative planet's orbital band (in yellow). The latter is a ring whose inner radius is the planet's perihelion and its outer radius the aphelion.

  • Left column, top: The minor planet's orbit is entirely inside the planet's —it is inner.
  • Left column, bottom: The minor planet's orbit is entirely outside the planet's —it is outer.
  • Middle column, top: The minor planet's orbit enters the planet's from inside without traversing it —it is inner-grazer.
  • Middle column, bottom: The minor planet's orbit enters the planet's from outside without traversing it —it is outer-grazer.
  • Right column, top: The minor planet's orbit is entirely within the planet's —it is co-orbital.
  • Right column, bottom: The minor planet's orbit traverses the planet's from inside to outside —it is crosser.
