Ruava
Ruava is a fictional planet located in the Cygnus X-1 system, approximately 6,070 light-years from Earth. It is described as a tidally locked exoplanet, meaning one side perpetually faces its star, resulting in extreme temperature differences between its light and dark hemispheres. The twilight zone, a narrow band between these two extremes, is theorized to be the most habitable region, potentially supporting liquid water and a unique ecosystem.
The planet's star is a blue supergiant, contributing to high levels of radiation on Ruava. Its atmosphere
