Alternate Orbital Body Placement

The following table represents a system for orbital placement based on Light minutes. This system will allow more than one planet to reside with in a Traveller orbit.

Select the orbit number per the Traveller rules and then flux for the actual position within that orbit.

Note: Multiple planets may now reside within a Traveller orbit. Just make sure they do not overlap. If they do, re-roll the flux dice for a new position.

Note: The further out each Traveller Orbit is the more room for for placing planets exist. You can further subdicvide these areas as you see fit to make as acurate an orbital distance as you like.
