Rogue, as used in reference to a planet, is usually understood to mean wandering. So exactly how does a planet which usually forms within a star system and attains an orbit around its star wind up wandering? Well, it turns out that planets interact gravitationally with one another and such gravitational interactions can lead to a planet being diverted into interstellar or inter galactic space depending on its trajectory. This ca occur due to interaction from other solar system planets, a nearby star, or else when a binary star system approaches a galactic black hole too closely and one of the planets falls in while the other's orbital momentum flings it into intergalactic space. Similar to two persons holding hands and twirling and suddenly letting go. Each will fly in opposite directions.
Of course, such planets are usually dark since they don't reflect the light of any star that they orbit. They can also arrive into a star system unexpectedly or their approach might be detected as they begin to reflect the light of the star they are approaching. A film called When World's Collide, based on a novel of the same name, was made. In the film, the rogue planet is depicted as scoring a direct hit on Earth.
