Antarctica surrounds the South Pole. The nearest landmass is South America, which is over 620 miles from the tip of the Antarctic Peninsula. 

Surface area 14 million square miles (36 million square kilometers).

There is no indigenous government, management of the Antarctic is organised through the legal framework of the Antarctic Treaty of 1959. Forty-three nations are now party to this agreement, and seven of those - the UK, Norway, Chile, France, Australia, Argentina and New Zealand - have historic claims on parts of the continent as national territory. The 1959 Antarctic Treaty preserves the status quo of the continent by neither recognizing nor rejecting the claims of these countries and by not allowing expansion in any way on the continent.

Antarctica currently has no economic activity apart from offshore fishing and tourism, and these are run by other nations (i.e. not the continent of Antarctica)

Going there on a tourist base:

The ships are ice strengthened and sail primarily to the Antarctic Peninsula region sometimes also including South Georgia and the Falkland Islands (Islas Malvinas). 

There have been occasional voyages to Antarctica by larger passenger vessels (up to 960 tourists), some of which conduct sightseeing cruises only without landings. Yacht travel is also very popular, and gives a smaller scale more intimate contact, though often without the luxuries and facilities of the larger Antarctica cruise ship.
