Orbites definition
The six diagrams above show the en:Sun at the center (orange point) and the orbital band (in yellow) of any en:planet. The edges of this band are defined by the en:perihelion (inner rim) and the en:aphelion (outer rim) of the planet.
- Top left: The minor planet's orbit is completely contained by that of the main planet —it's an inner cruiser.
- Bottom left, : The orbit of the minor planet completely contains that of the main planet —it's an outer cruiser.
- Top center: The orbit of the minor planet overlaps that of the main planet from the interior without completely crossing it —it's an inner grazer. Aten asteroids are inner grazers or crossers.
- Bottom center: The orbit of the minor planet overlaps that of the main planet from the exterior without completely crossing it —it's a outer grazer. Apollo asteroids are outer grazers or crossers.
- Top right: The minor planet's orbit is completely confined by that of the main planet —it's co-orbital.
- Bottom right: The minor planet's orbit crosses the main planet's orbit from the inside to the outside —it's a crosser.

BahnkreuzerAls Bahnkreuzer werden Asteroiden bezeichnet, deren Umlaufbahn die eines Planeten kreuzt, d. h. Perihel und Aphel liegen jeweils außerhalb bzw. innerhalb einer Planetenumlaufbahn, was in der meist hohen Exzentrizität dieser Objekte begründet ist. Wird das Gebiet der Planetenbahn nicht vollständig gekreuzt, sondern lediglich teilweise durchdrungen, spricht man von Bahnstreifern. Zu den Bahnkreuzern zählen auch Objekte, die sich in einer koorbitalen Umlaufbahn zu dem jeweiligen Planeten bewegen. .. weiterlesen
