Nuuk vs Sun

Informations

Nuuk (Greenlandic pronunciation: [nuːk], Danish: [ˈnu(ː)k]; Danish: Godthåb [ˈkʌtˌhɔˀp]) is the capital and largest city of Greenland. Nuuk is the seat of government and the country's largest cultural and economic centre. The major cities from other countries closest to the capital are Iqaluit and St. John's in Canada and Reykjavík in Iceland. Nuuk contains almost a third of Greenland's population and its tallest building. Nuuk is also the seat of government for the Sermersooq municipality. In January 2020, it had a population of 18,326.The city was founded in 1728 by the Dano-Norwegian governor Claus Paarss when he relocated Hans Egede's earlier Hope Colony (Haabets Koloni) to the mainland, and was named Godthåb ("Good Hope"). The city officially adopted its current name in 1979, although the name "Godthåb" remained in use in Danish.

"Nuuk" is the Greenlandic word for "cape" (Danish: næs). It is so named because of its position at the end of the Nuup Kangerlua fjord on the eastern shore of the Labrador Sea. Its latitude, at 64°11' N, makes it the world's northernmost capital, only a few kilometres farther north than the Icelandic capital Reykjavík. The campus of the University of Greenland, hosting Statistics Greenland, and the main holdings of the Public and National Library of Greenland are at the northern end of the district, near the road to the Nuuk Airport.Nuuk receives its electric power mainly from the renewable energy-powered Buksefjord hydroelectric power plant by way of a 132 kV powerline crossing Ameralik fjord over a distance of 5,376 m (17,638 ft), the world's longest free span.

The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as light and infrared radiation. It is by far the most important source of energy for life on Earth. Its diameter is about 1.39 million kilometres (864,000 miles), or 109 times that of Earth, and its mass is about 330,000 times that of Earth. It accounts for about 99.86% of the total mass of the Solar System. Roughly three quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron.The Sun is a G-type main-sequence star (G2V) based on its spectral class. As such, it is informally and not completely accurately referred to as a yellow dwarf (its light is closer to white than yellow). It formed approximately 4.6 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into an orbiting disk that became the Solar System. The central mass became so hot and dense that it eventually initiated nuclear fusion in its core. It is thought that almost all stars form by this process.

In its core the Sun currently fuses about 600 million tons of hydrogen into helium every second, converting 4 million tons of matter into energy every second as a result. This energy, which can take between 10,000 and 170,000 years to escape the core, is the source of the Sun's light and heat. When hydrogen fusion in its core has diminished to the point at which the Sun is no longer in hydrostatic equilibrium, its core will undergo a marked increase in density and temperature while its outer layers expand, eventually transforming the Sun into a red giant. It is calculated that the Sun will become sufficiently large to engulf the current orbits of Mercury and Venus, and render Earth uninhabitable – but not for about five billion years. After this, it will shed its outer layers and become a dense type of cooling star known as a white dwarf, and no longer produce energy by fusion, but still glow and give off heat from its previous fusion. The enormous effect of the Sun on Earth has been recognized since prehistoric times. The Sun has been regarded by some cultures as a deity. The synodic rotation of Earth and its orbit around the Sun are the basis of solar calendars, one of which is the predominant calendar in use today.
