Asia is the largest of the five continents on Planet Earth in area and population. The term Asia refers conventionally to the eastern portion of the Eurasian landmass plus the island country of Japan and the island nations of Maritime Southeast Asia.
The continent is situated almost entirely north of the equator except for some Southeast Asian islands. Asia is connected to Africa by the Isthmus of Suez and borders Europe (part of the same landmass) along the Ural Mountains and across the Caspian Sea.
