The snow line is a boundary in the solar system beyond which ices such as water, carbon dioxide, methane and ammonia are found. Inside the snow line, these ices cannot exist in a stable form due to the greater solar radiation and higher temperatures. Therefore, the snow line marks the distance from the Sun beyond which volatile compounds can condense into solid ice grains or snow.
