Asia is Earth's largest continent at 17,139,000 sq mi with an approximate population of 3.3 billion people. That's nearly three fifths of the planet's total population!

Asia's border with Europe—which, geographically, may be regarded as a peninsula of the Eurasian landmass—lies approximately along the Urals, the Ural River, the Caspian Sea, the Caucasus, the Black Sea, the Bosporus and Dardanelles straits, and the Aegean Sea. The connection of Asia with Africa is broken only by the Suez Canal between the Mediterranean Sea and the Red Sea. In the far northeast of Asia, Siberia is separated from North America by the Bering Strait. The continent of Asia is washed on the S by the Gulf of Aden, the Arabian Sea, and the Bay of Bengal; on the E by the South China Sea, East China Sea, Yellow Sea, Sea of Japan, Sea of Okhotsk, and Bering Sea; and on the N by the Arctic Ocean.
