Distance between Boise, Idaho, USA and the Arctic Circle
2555 km = 1587 miles
During our calculation of the distance to the Arctic Circle we make two assumptions:
- We assume a spherical Earth as a close approximation of the true shape of the Earth (an oblate spheroid). The distance is calculated as great-circle or orthodromic distance on the surface of a sphere.
- We calculate the distance between a point on the Earth’s surface and the Arctic Circle as the length of the arc of the meridian passing through this point and crossing the Arctic Circle.

The Arctic CircleThe Arctic Circle is a circle of latitude or parallel on the Earth's surface. The polar night and the midnight sun phenomena can be observed to the north of the Arctic Circle.
During the midnight sun there is no sunset and the Sun is over the horizon continuously for 24 hours or more.
During the polar night there is no sunrise and the Sun is below the horizon continuously for 24 hours or more.
For the points on the Earth's surface located at the Arctic Circle the polar night and the midnight sun coincide with the winter solstice and the summer solstice correspondingly and their duration equals 24 hours.
For the points on the Earth's surface located to the north of the Arctic Circle the duration of the polar night and the midnight sun grows with latitude.
The latitude of the Arctic Circle depends on the tilt of the Earth's axis which changes with time.
The current latitude of the Arctic Circle equals 66°33′43″ N.
