Main article: Geography of the Soviet Union
With an area of 22,402,200 square kilometres (8,649,500 sq mi), the Soviet Union was the world's largest state, a status that is retained by the Russian Federation.Covering a sixth of the Earth's land surface, its size was comparable to that of North America. The European portion accounted for a quarter of the country's area, and was the cultural and economic center. The eastern part in Asia extended to the Pacific Ocean to the east and Afghanistan to the south, and, except some areas in Central Asia, was much less populous. It spanned over 10,000 kilometres (6,200 mi) east to west across 11 time zones, and over 7,200 kilometres (4,500 mi) north to south. It had five climate zones: tundra, taiga, steppes, desert, and mountains.
The Soviet Union had the world's longest boundary, like Russia, measuring over 60,000 kilometres (37,000 mi), or 1 1/2 circumferences of the Earth. Two-thirds of it were a coastline. Across the Bering Strait was the United States. The Soviet Union bordered Afghanistan, China, Czechoslovakia, Finland, Hungary, Iran, Mongolia, North Korea, Norway, Poland, Romania, and Turkey from 1945 to 1991.
The Soviet Union's highest mountain was Communism Peak (now Ismoil Somoni Peak) in Tajikistan, at 7,495 metres (24,590 ft). The Soviet Union also included most of the world's largest lake, the Caspian Sea (shared with Iran), and also Lake Baikal, the world's largest freshwater and deepest lake, an internal body of water in Russia.
