Distance between St Louis, Missouri, USA and the Antarctic Circle
11710 km = 7276 miles
During our calculation of the distance to the Antarctic 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 Antarctic Circle as the length of the arc of the meridian passing through this point and crossing the Antarctic Circle.

The Antarctic CircleThe Antarctic 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 south of the Antarctic 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 Antarctic 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 south of the Antarctic Circle the duration of the polar night and the midnight sun grows with latitude.
The latitude of the Antarctic Circle depends on the tilt of the Earth's axis which changes with time.
The current latitude of the Antarctic Circle equals 66°33′43″ S.
