what degrees does the arctic circle sit at
The position of the Arctic Circle is not fixed; as of 22 January 2018, it runs 66 ° 33 ′ 47.0" north of the Equator. Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of 2 ° over a 40,000-year period, due to tidal forces resulting from the orbit of the Moon. Consequently, the Arctic Circle is currently drifting northwards at a speed of about 15 metres (49 feet) per year.
