Rogue Planets

Rogue planets are celestial bodies that do not orbit a star and instead travel through interstellar space. Unlike traditional planets, which are bound by the gravitational pull of a star, rogue planets have likely formed around a star but have been ejected due to gravitational interactions or collisions. These solitary planets can vary in size, composition, and temperature, and they may possess atmospheres and geological features similar to those of planets that do orbit stars. The study of rogue planets is significant in understanding planetary formation and the dynamics of planetary systems, as well as the potential for life in the cosmos, as some rogue planets may have internal heat sources that could sustain subsurface environments.
