Spacecraft.C3 Property

Top 

Description

Returns the characteristic energy of the calling Spacecraft relative to its CentralBody. The characteristic energy is a measure of the excess specific energy over that required to escape from the CentralBody. For a Spacecraft in a non-escape trajectory, the characteristic energy will be less than 0. For a Spacecraft in a parabolic trajectory, the characteristic energy will be equal to 0. A Spacecraft in a hyperbolic trajectory will have a characteristic energy that is equal to the Hyperbolic Excess Velocity squared.
