From an average distance of 36 million miles (58 million kilometers), Mercury is 0.4 astronomical units away from the Sun. However Mercury also has some very cold areas that are able to support frozen water (ice). Comets or meteorites may have delivered ice there, or water vapor may have outgassed from the planet's interior and frozen out at the poles. There’s water on Earth, obviously. Mercury cannot have liquid water on the surface because it doesn't have any atmosphere so liquid water would immediately freeze (if in shadow) or evaporate (if in sunlight).
