Gravitational slingshot refers to use of the relative movement and gravity of a celestial body to alter the path and speed of a spacecraft. This maneuver is commonly known as "slingshot orbit", and has been used in numerous occasions. [[Preston Cole]] was known to be adept in using a planet's gravity well to his advantage in space combat.<ref>'''[[Halo: Evolutions - Essential Tales of the Halo Universe]]''', "[[The Impossible Life and the Possible Death of Preston J.

The [[Forerunner]]s were able to develop [[Gravity well|technology]] capable of forming localized artificial gravity wells. Functioning akin to a [[wikipedia:Tractor beam|tractor beam]], the large devices are capable of pulling in and anchoring objects such as spacecraft.<ref>'''[[Halo 4]]''', campaign level ''[[Reclaimer (level)|Reclaimer]]''</ref> | The [[Forerunner]]s were able to develop [[Gravity well|technology]] capable of forming localized artificial gravity wells.
