It extends from the Baltic Sea in the west to the Pacific Ocean in the east, and from the Arctic Ocean in the north to the Black Sea and the Caspian Sea in the south.

The Soviet Union, officially the Union of Soviet Socialist Republics (USSR), was a federal socialist state in Northern Eurasia that existed from 1922 to 1991. Nominally a union of multiple national Soviet republics, it was a one-party state (until 1990) governed by the Communist Party, with Moscow as its capital in its largest republic, the Russian SFSR. It was the largest country in the world by surface area, spanning over 10,000 kilometers (6,200 mi) east to west across 11 time zones and over 7,200 kilometers (4,500 mi) north to south.
