Megastructures Shkadov Thruster 1

The Shkadov thruster (named after Dr. Leonid Mikhailovich Shkadov), also known as a Class A Stellar Engine, accelerates a star through space by selectively reflecting or absorbing light on one side of the star's surface. This could be used to move your own sun to a different location in the cosmos, or move a potential dangerous sun (one that's likely to go super nova) away from damaging your system.
