Arctic Circle Map
The Arctic Circle is defined as the most southerly location in the Northern Hemisphere where the sun stays above or below the horizon for 24 hours. North of the Arctic curve, the sun will be above/below the horizon for 24 continuous hours at least once per year on the Winter Solstice (December 21st or 22nd) or Summer Solstice (June 20th or 21st). At the Summer Solstice in the Arctic the sun will be visible throughout the day including midnight while during the Winter Solstice day the sun will not appear at all.
The Arctic Circle in marked in blue and the July 10 °C mean isotherm in red. The map is courtesy of the CIA. Yes! They are useful for something other than assassination!
The Arctic Circle as outlined on this map represents a global view at 90° N 0° to the planet, displaying the seven countries included in the circle; Canada, Finland, Greenland, Norway, Sweden, Russia and the United States of America.

The Arctic, unlike the Antarctic, does have indigenous
peoples and polar bears, but no penguins unless they are seriously adrift in their navigation. Both poles are visited by abundant numbers of whales and seals.

BTW, the word Arctic is derived from Arktos, 'the bear' in Greek, due to the Great Bear constellation above the North Pole.
