Argentina ⁱ/ˌɑrdʒənˈtiːnə/, officially the Argentine Republic (Spanish: República Argentina [reˈpuβlika aɾxenˈtina]), is the second largest country in both South America and the Latin America region.

The country is a federation of 23 provinces and the autonomous city of Buenos Aires, its capital and largest city. It is the eighth-largest country in the world by land area and the largest among Spanish-speaking nations by geographical area of 2,780,400 km2 and is the fourth by population, with over 41 million people. Argentina is a founding member of the United Nations, Mercosur, the Union of South American Nations, the Organization of Ibero-American States, the World Bank Group and the World Trade Organization, and is one of the G-15 and G-20 major economies.

Patagonia is a region located at the southern end of South America, shared by Argentina and Chile. The region comprises the southern section of the Andes mountains to the southwest towards the Pacific ocean and from the east of the mountain range to the valleys it follows the Colorado River south towards Carmen de Patagones in the Atlantic Ocean. To the west, it includes the territory of Valdivia through Tierra del Fuego archipelago.

The name Patagonia comes from the word patagón used by Magellan in 1520 to describe the native people that his expedition thought to be giants. It is now believed the Patagons were actually Tehuelches with an average height of 180 cm (~5′11″) compared to the 155 cm (~5′1″) average for Europeans of the time.

The Argentine portion of Patagonia includes the provinces of Neuquén, Río Negro, Chubut and Santa Cruz, as well as the eastern portion of Tierra del Fuego archipelago and the southernmost department of Buenos Aires province: Patagones. The Argentine politico-economic Patagonic Region includes the Province of La Pampa.

The Southern Hemisphere is that part of a rotating astronomical body that lies south of the equator. The word hemisphere (from the Greek word σφαιρα (sphere) +ημι (half)) literally means 'half ball' or "half sphere". It is also that half of the celestial sphere south of the celestial equator.

On Earth the Southern Hemisphere contains all or parts of four continents (Antarctica, Australia, about 9/10 of South America and southern third of Africa), four oceans (South Atlantic, Indian, South Pacific, and Southern) and most of Oceania. Several islands off the Asian continental mainland are also in the Southern Hemisphere. Due to the tilt of Earth's rotation relative to the Sun and the ecliptic plane, summer is from December to March and winter is from June to September. September 22 or 23 is the vernal equinox and March 20 or 21 is the autumnal equinox.
