Midnight Sun: A midnight sun is a natural phenomenon that occurs around the summer solstice in places north of the Arctic Circle or south of the Antarctic Circle, when the Sun remains visible at midnight. The number of days per year with a midnight sun increases as one moves closer to either pole. Although approximately bound by the polar circles, a midnight sun can be seen as much as 55 miles (90 km) outside the polar circle and the exact latitudes of the farthest reaches of midnight sun depend on topography and vary slightly year-to-year.
