Gravity assist - Wikipedia
WEBA gravity assist, gravity assist maneuver, swing-by, or generally a gravitational slingshot in orbital mechanics, is a type of spaceflight flyby which makes use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and ...

Space Travel: How Do Gravitational Slingshots Work? - Forbes
WEBJan 6, 2017 · The way a gravitational slingshot is often explained is that a small body (e.g. a space probe) uses the gravitational attraction of a large one (e.g. a planet) to speed itself up.
WEBA gravity slingshot is a maneuver that results in an energy transfer between an approaching spacecraft and large celestial body. Can be used to speed up, slow down, and redirect vehicles. When the spacecraft approaches, it gains speed as it falls towards the planet, then gains enough speed to surpass escape velocity (V e) Motivation
