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 ...
Basics of Spaceflight: A Gravity Assist Primer - NASA Science
WEBThe "gravity assist" flyby technique can add or subtract momentum to increase or decrease the energy of a spacecraft's orbit. Generally it has been used in solar orbit, to increase a spacecraft's velocity and propel it outward in the solar system, much farther away from the Sun than its launch vehicle would have been capable of doing.

Gravitational Slingshot: How Did Gravity Assist Voyager 1 & 2?
WEBOct 19, 2023 · A gravitational slingshot is when a spacecraft uses the gravity of a planet to change its trajectory. The gravity of the planet pulls on the spacecraft, and as the spacecraft swings around the planet, it gains speed. This speed boost can be used to help the spacecraft escape the solar system.
How Does a Martian -Style Gravity Assist Actually Work?
WEBJan 3, 2019 · The first question is easy—a gravity assist (also called a gravity slingshot) is a space maneuver in which a spacecraft gets a speed boost by moving past a planet.

WEBNov 4, 2015 · A gravitational slingshot, also called a gravity assist, uses the gravity of other objects in space, such as planets, to change the momentum of an object, such as a spacecraft. To understand how this happens, it is crucial to know about gravity.
orbit - How does a gravity slingshot actually work? - Astronomy …
WEBJul 22, 2014 · The "gravity slingshot" maneuver we've seen in sci-fi and even used by our own spacecraft relies on the physics of hyperbolic orbits, where an object both enters and exits the orbit before making a single lap around the planet/moon/etc.
How does the gravitational slingshot effect work? - Physics Network
WEBMay 19, 2023 · The effect known as the gravity assist or slingshot effect is a way of using the motion of a planet to accelerate a space probe on its journey towards the outer planets. Think of a space probe on a journey to Neptune. On its way it will have to pass Jupiter – the largest planet in the Solar System.
Gravity-assist “Slingshot,” Part 1: Background and principle
WEBDec 6, 2018 · The story of the slingshot effect, how it was quantified, and how it is used is fascinating — and relies largely on the work of a single student with insight and determination.
Gravity assist - Simple English Wikipedia, the free encyclopedia
WEBA gravitational slingshot, gravity assist maneuver or swing-by is the use of the relative movement and gravity of a planet to alter the path and speed of a spacecraft. This helps the spacecraft to save fuel, time, and expense.
