Question: How big is the continent encompassing Auriga Nunataks in square miles?

full_context: Document 1: Antarctica: Due to its location at the South Pole, Antarctica receives relatively little solar radiation. This means that it is a very cold continent where water is mostly in the form of ice. Precipitation is low (most of Antarctica is a desert) and almost always in the form of snow, which accumulates and forms a giant ice sheet which covers the land. Parts of this ice sheet form moving glaciers known as ice streams, which flow towards the edges of the continent. Next to the continental shore are many ice shelves. These are floating extensions of outflowing glaciers from the continental ice mass. Offshore, temperatures are also low enough that ice is formed from seawater through most of the year. It is important to understand the various types of Antarctic ice to understand possible effects on sea levels and the implications of global cooling.
Document 2: Stellar Crests: Stellar Crests () is a four prominent snow-covered peaks, rising to about 2,000 m, surmounting LeMay Range west of the north part of Planet Heights in central Alexander Island, Antarctica. The peaks were first mapped from air photos taken by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960. Named by the United Kingdom Antarctic Place-Names Committee for their proximity to features named for planets and their satellites.
Document 3: Auriga Nunataks: The Auriga Nunataks () are a small group of nunataks in Palmer Land, Antarctica, located east of Wade Point at the head of Bertram Glacier. The highest of these rises to a sharp peak and is visible for a great distance. They were named by the UK Antarctic Place-Names Committee after the constellation of Auriga.
Document 4: Wilkes Land: Wilkes Land is a large district of land in eastern Antarctica, formally claimed by Australia as part of the Australian Antarctic Territory, though the validity of this claim has been placed for the period of the operation of the Antarctic Treaty, to which Australia is a signatory. It fronts on the southern Indian Ocean between Queen Mary Coast and Adelie Land, extending from Cape Hordern in 100°31' E to Pourquoi Pas Point, in 136°11' E. The region extends as a sector about 2600 km towards the South Pole, with an estimated land area of 2,600,000 km², mostly glaciated. It is further subdivided in the following coastal areas which can also be thought of as sectors extending to the South Pole:
Document 5: Mount Lepus: Mount Lepus () is a large rocky massif separated into two distinct sections by a deep saddle, standing between Millett Glacier and Bertram Glacier, about east of Wade Point on the west coast of Palmer Land, Antarctica. It was named by the UK Antarctic Place-Names Committee after the constellation of Lepus.
Document 6: Vesta Nunataks: The Vesta Nunataks () is a small group of nunataks rising to about 1,200 m, lying between Grikurov Ridge in the LeMay Range and Aeolus Ridge in Planet Heights, situated near the east coast of Alexander Island, Antarctica. In association with the names of planets and their satellites in this area, they were named after Vesta, an asteroid that lies between the orbits of Mars and Jupiter. They were named by United Kingdom Antarctic Place-Names Committee in 1987.
Document 7: Tufft Nunatak: Tufft Nunatak () is a small nunatak 3 nautical miles (6 km) southwest of Mount Bradley and 4.6 km south of Senokos Nunatak, Trinity Peninsula in Graham Land, Antarctica. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) for Roger Tufft of the Falkland Islands Dependencies Survey (FIDS), a member of the reconnaissance party for the Detroit Plateau journey in February 1957.
Document 8: Wilkes Land: Wilkes Land is a large district of land in eastern Antarctica, formally claimed by Australia as part of the Australian Antarctic Territory, though the validity of this claim has been placed for the period of the operation of the Antarctic Treaty, to which Australia is a signatory. It fronts on the southern Indian Ocean between Queen Mary Coast and Adelie Land, extending from Cape Hordern in 100°31' E to Pourquoi Pas Point, in 136°11' E. The region extends as a sector about 2600 km towards the South Pole, with an estimated land area of 2,600,000 km², mostly glaciated. It is further subdivided in the following coastal areas which can also be thought of as sectors extending to the South Pole:
Document 9: Urguri Nunatak: Urguri Nunatak (, ‘Nunatak Urguri’ \'nu-na-tak ur-'gu-ri\) is the rocky hill rising to 560 m in the east foothills of Laclavère Plateau on Trinity Peninsula in Graham Land, Antarctica. It is overlooking Mott Snowfield to the north.
Document 10: Antarctica: Antarctica is colder than the Arctic for three reasons. First, much of the continent is more than 3,000 m (9,800 ft) above sea level, and temperature decreases with elevation in the troposphere. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. Third, the Earth is at aphelion in July (i.e., the Earth is farthest from the Sun in the Antarctic winter), and the Earth is at perihelion in January (i.e., the Earth is closest to the Sun in the Antarctic summer). The orbital distance contributes to a colder Antarctic winter (and a warmer Antarctic summer) but the first two effects have more impact.
Document 11: Antarctic Plate: The Antarctic Plate is a tectonic plate containing the continent of Antarctica, the Kerguelen Plateau and extending outward under the surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea), the Antarctic plate began moving the continent of Antarctica south to its present isolated location causing the continent to develop a much colder climate. The Antarctic Plate is bounded almost entirely by extensional mid-ocean ridge systems. The adjoining plates are the Nazca Plate, the South American Plate, the African Plate, the Somali Plate, the Indo-Australian Plate, the Pacific Plate, and, across a transform boundary, the Scotia Plate.
Document 12: Antarctica: Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. It covers more than 14,000,000 km2 (5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations, as the following table shows:
Document 13: Gemini Nunataks: The Gemini Nunataks () are two nunataks of similar size and appearance in a prominent position near the west wall of Shackleton Glacier, Antarctica, just southeast of Mount Cole. They were named by F. Alton Wade, leader of the Texas Tech Shackleton Glacier Expedition, 1962–63, after the constellation Gemini, which contains the twin stars Castor and Pollux.
Document 14: Antarctica: Antarctica (US English i/æntˈɑːrktɪkə/, UK English /ænˈtɑːktɪkə/ or /ænˈtɑːtɪkə/ or /ænˈɑːtɪkə/)[Note 1] is Earth's southernmost continent, containing the geographic South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres (5,400,000 square miles), it is the fifth-largest continent in area after Asia, Africa, North America, and South America. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.
Document 15: Sirius Cliffs: Sirius Cliffs () is a conspicuous isolated nunatak with steep rock cliffs all along its north face, located between Mount Lepus and Procyon Peaks on the south side of Millett Glacier, in Palmer Land, Antarctica. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) after the star Sirius in the constellation of Canis Major.
