Overview
Antarctica is Earth's southernmost and least-populated continent, rather than a country. It has no permanent residents, no government, and no native population; instead, it is governed collectively by international agreement. Situated almost entirely south of the Antarctic Circle, Antarctica is surrounded by the Southern Ocean and contains the geographic South Pole, one of the most extreme and remote points on the planet.
Size and Geography
Antarctica is the fifth-largest continent, making it roughly 40% larger than Europe. It covers an area of approximately 14,200,000 square kilometers (5,500,000 square miles), a vast expanse that places it ahead of Europe and Australia in terms of total landmass, though still smaller than Asia, Africa, North America, and South America.
The Antarctic Ice Sheet
Antarctica's defining geographic feature is its enormous ice sheet, which covers most of the continent. This ice sheet has an average thickness of about 1.9 kilometers (1.2 miles), making it the largest single mass of ice on Earth. The sheer scale of this ice cover shapes nearly every aspect of the continent's climate, ecology, and accessibility.

A Continent, Not a Country
Unlike other landmasses that host multiple sovereign nations, Antarctica is not divided into countries. It has no indigenous population and no permanent residents; the people who spend time there are primarily scientists and support staff stationed at research bases. This unique status makes Antarctica the only continent without a native population or established national governments in the traditional sense.
