Orbital Period

The Orbital Period of an object is the time required for the object to complete one orbit around its Orbital Parent. The Orbital Period of an object on a parabolic or hyperbolic trajectory (where Eccentricity >= 1) is undefined, and this property will be read-only.

Location
The Orbital Period property of an object can be found in the Motion section of the Overview tab as well as at the top of the Orbital Elements section of the Motion tab, if the object has a defined orbit.

Units
Orbital Period can be viewed and editing using the following units:


 * Gigayears (G years) = 109 years
 * Megayears (M years) = 106 years
 * Years (years) = 365.25 days
 * Months (months) = 1/12 years
 * Days (days) = 24 hours
 * Hours (hours) = 60 mins
 * Minutes (mins) = 60 sec
 * Seconds (sec) is the SI base unit for time

Orbit
Changing the Orbital Period of an object will change the size of its orbit (specifically, the Semi-Major Axis of the orbit).
