Exovalintaan

Exovalintaan is a hypothetical astronomical phenomenon that describes the potential ejection of a planet from its star system. While not yet definitively observed, the concept arises from simulations and theoretical models of planetary system dynamics. Such an event could occur due to gravitational interactions between planets within a system, particularly in systems with multiple massive planets or in close proximity. A significant gravitational encounter, perhaps involving a close pass between two large planets, could impart enough momentum to one of them to overcome the gravitational pull of the host star and send it hurtling into interstellar space.

The expelled planet, now an "exovaltin," would become a rogue planet, drifting through the galaxy without a host star. These objects would be incredibly difficult to detect, as they would not emit their own light and would only be visible through their gravitational influence on other objects or potentially through emitted infrared radiation if they still retained significant internal heat. The study of exovaltins is an area of theoretical astrophysics, with implications for understanding planetary system formation and evolution, as well as the potential for life to exist on rogue planets.
