The Arctic Circle is an invisible ring on our planet, encompassing the Arctic region. The Arctic Circle lines the boundary of an area in which the sun does not set on some days in summer (an Arctic phenomenon called the Midnight Sun) and does not rise in winter (which is called the Polar Nights).

The center of the Arctic Circle is the North Pole, which makes the Arctic Circle the region of the Northern Hemisphere surrounding the North Pole.

The Arctic Circle is also one of the five major named circles of latitude on the globe.

Scandinavia puts on quite a show of three natural phenomena which occur year-round inside the Arctic Circle. This includes the Northern Lights, the Midnight Sun, and the Polar Nights.
