$\begingroup$ So doesn't that mean that free falling objects don't actually follow geodesics even without drag from atmosphere. So only objects moving in straight line with no gravity are truly following geodesics then? $\endgroup$

$\begingroup$ As long as the object is in free fall (no external forces) it will follow a geodesic. A geodesic is the equivalent of a straight line (the shortest distance between two points) when spacetime is curved , but it is definitely not straight. $\endgroup$

$\begingroup$ @Milton The system is radiating energy-momentum, so the geodesics are changing. $\endgroup$
