Russia: The Country Spanning Three Oceans, Arctic Circle, and Tropic of Cancer

The country described is Russia.

Geographic Extremes

• Three Oceans: Arctic Ocean (north), Pacific Ocean (east), Atlantic Ocean (west—via Baltic, Black, and Caspian seas connections).
• Arctic Circle: Crosses northern Russia (Murmansk, Norilsk, Siberian coast).
• Tropic of Cancer: Does not cross Russia. The Tropic of Cancer (23.5°N) passes through Mexico, India, China, etc. Russia’s southernmost point is ~41°N (Dagestan). The original prompt contains an error.

Correction

Russia spans the Arctic Circle and touches three oceans, but it lies entirely north of the Tropic of Cancer. The country that fits all three criteria (three oceans, Arctic Circle, Tropic of Cancer) does not exist. The closest is United States (Arctic Ocean via Alaska, Pacific, Atlantic, Arctic Circle in Alaska, Tropic of Cancer in Hawaii)—but Hawaii is not contiguous.

Russia remains the only country bordering three oceans and crossing the Arctic Circle.
