Star lifting

Star lifting is a method used by astronomers to make small adjustments to the orbit of large objects. It works by using a spacecraft, which is the “star lifter”, to push the object in a particular direction, creating a small but gradual change in its orbit. This can be used for many things, such as helping to move a satellite into a better orbit that matches its mission, or helping to move a large asteroid away from Earth. In order for star lifting to work, it needs to be very carefully planned and measured. By using the spacecraft to create tiny pushes it is possible to easily and safely move the object without using large amounts of fuel.
