% Convert orbital velocity to C3 energy C3 is a measure of the excess specific energy over that required to just barely escape from a massive body. C3 is twice the specific orbital energy of the escaping object. A negative C3 means the object is in orbit while a positive C3 means it has escaped. Type VToC3 for a heliocentric demo. -------------------------------------------------------------------------- Form: c3 = VToC3( v, r, mu ) -------------------------------------------------------------------------- ------ Inputs ------ v (1,:) Velocity (km/s) r (1,1) Distance from central body (km) mu (1,1) Gravitational parameter (default: sun) ------- Outputs ------- c3 (1,:) C3 characteristic energy (km^2/s^2) --------------------------------------------------------------------------
