Aberdeen ( (listen); Scots: Aiberdeen, listen ; Scottish Gaelic: Obar Dheathain [opəɾ ˈɛ.ɛɲ]; Latin: Aberdonia) is a city in northeast Scotland. It is Scotland's third most populous city, one of Scotland's 32 local government council areas (as Aberdeen City) and the United Kingdom's 39th most populous built-up area, with an official 2018 population estimate of 198,880 for the city of Aberdeen and 227,560 for the local council area.During the mid-18th to mid-20th centuries, Aberdeen's buildings incorporated locally quarried grey granite, which can sparkle like silver because of its high mica content. Since the discovery of North Sea oil in the 1970s, Aberdeen has been known as the off-shore oil capital of Europe. The area around Aberdeen has been settled for at least 8,000 years, when prehistoric villages lay around the mouths of the rivers Dee and Don. The city has a long, sandy coastline and a marine climate, the latter resulting in chilly summers and mild winters. Aberdeen received Royal burgh status from David I of Scotland (1124–1153), transforming the city economically. The city has two universities, the University of Aberdeen, founded in 1495, and Robert Gordon University, which was awarded university status in 1992, making Aberdeen the educational centre of north-east Scotland.

The traditional industries of fishing, paper-making, shipbuilding, and textiles have been overtaken by the oil industry and Aberdeen's seaport. Aberdeen Heliport is one of the busiest commercial heliports in the world and the seaport is the largest in the north-east of Scotland.Aberdeen used to host the Aberdeen International Youth Festival, a major international event which attracted up to 1000 of the most talented young performing arts companies but the council ended funding in 2017 and the festival was wound up in 2018. In 2015, Mercer named Aberdeen the 57th most liveable city in the world, as well as the fourth most liveable city in Britain. In 2012, HSBC named Aberdeen as a leading business hub and one of eight 'super cities' spearheading the UK's economy, marking it as the only city in Scotland to receive this accolade. In 2018, Aberdeen was found to be the best city in the UK to start a business in a study released by card payment firm Paymentsense.

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.
