icy moon

An icy moon is a natural satellite that is predominantly covered with a layer of ice, often composed of water or other frozen compounds. These moons orbit planets and can have subsurface oceans beneath their icy crusts, potentially creating environments with the conditions necessary for life. Examples include Europa and Enceladus in our solar system. Their icy surfaces can feature cracks, geysers, or plumes, indicating active geological processes. Studying icy moons helps scientists understand planetary systems, the potential for life beyond Earth, and the environment of outer space worlds.
