The Arctic Circle passes through the state of Alaska in the United States. This imaginary line of latitude is located at approximately 66.5 degrees north of the Equator. Alaska is the only U.S. state that the Arctic Circle crosses, making it a unique location for experiencing the phenomena associated with this region, such as the midnight sun and the polar night.
The Arctic Circle also passes through several other countries, including Canada, Greenland, Norway, Sweden, Finland, and Russia. However, in the context of the United States, Alaska stands out as the sole state that lies within this northernmost circle of latitude.
