Ice planet - Wikipedia
Ice planets would have surface temperatures below 260 K (−13 °C) if composed primarily of water, below 180 K (−93 °C) if primarily composed of CO 2 and ammonia, and below 80 K (−193 °C) if composed primarily of methane. On the surface, ice planets are hostile to life forms like those living on Earth because they are extremely cold.
