Flyby anomaly, swing-by anomaly, planetary orbits
‘Flyby anomaly’ is a significant but unaccounted apparent increase or reduction in linear velocity of a spacecraft during Earth-flybys. This phenomenon could not be explained by current physical laws. This article attempts to show that the noticed discrepancies are apparent and they are produced by faulty geometry used in contemporary laws of planetary motion. In reality, spacecraft and external efforts on it behave normally. There are no causes or actions, which vary spacecraft’s linear velocity during Earth-flybys. There is no basis for assumption of strange ‘forces’ or mysterious effects on or about the spacecraft.
