Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In astronautics, the Oberth effect or powered flyby is an effect by which the application of an impulse, typically from the use of a rocket engine, close to a gravitational body (where the gravity potential is low) can give much more kinetic energy and a much bigger change in final speed (i.e. greater specific energy) than the same impulse applied further from the body for the same initial orbit. It is named for Hermann Oberth, the Romanian-born, German physicist and a founder of modern rocketry. For the Oberth effect to be most effective, the vehicle must be able to generate as much impulse as possible at the lowest possible altitude; thus the Oberth effect is often far less useful for low-thrust reaction engines such as ion drives, which have a low propellant flow rate.
