Sun vs Nuremberg

Informations

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.

Nuremberg ( NEWR-əm-burg; German: Nürnberg [ˈnʏʁnbɛʁk] (listen); in the local East Franconian dialect: Närmberch) is the second-largest city of the German federal state of Bavaria after its capital Munich, and its 511,628 (2016) inhabitants make it the 14th-largest city in Germany. On the Pegnitz River (from its confluence with the Rednitz in Fürth onwards: Regnitz, a tributary of the River Main) and the Rhine–Main–Danube Canal, it lies in the Bavarian administrative region of Middle Franconia, and is the largest city and the unofficial capital of Franconia. Nuremberg forms a continuous conurbation with the neighbouring cities of Fürth, Erlangen and Schwabach with a total population of 798,867 (2018), while the larger Nuremberg Metropolitan Region has approximately 3.6 million inhabitants. The city lies about 170 kilometres (110 mi) north of Munich. It is the largest city in the East Franconian dialect area (colloquially: "Franconian"; German: Fränkisch), Nuremberg was one of the host cities of the 2006 FIFA World Cup. There are many institutions of higher education in the city, including the University of Erlangen-Nuremberg (Friedrich-Alexander-Universität Erlangen-Nürnberg).

With 39,780 students in 2017, it is Bavaria's third-largest and Germany's 11th-largest university, with campuses in Erlangen and Nuremberg and a university hospital in Erlangen (Universitätsklinikum Erlangen). Technische Hochschule Nürnberg Georg Simon Ohm and Hochschule für Musik Nürnberg are also located within the city. Nuremberg Airport (Flughafen Nürnberg “Albrecht Dürer“) is the second-busiest airport in Bavaria after Munich Airport, and the tenth-busiest airport in Germany. Staatstheater Nürnberg is one of the five Bavarian state theatres, showing operas, operettas, musicals, and ballets (main venue: Nuremberg Opera House), plays (main venue: Schauspielhaus Nürnberg), as well as concerts (main venue: Meistersingerhalle). Its orchestra, Staatsphilharmonie Nürnberg, is Bavaria's second-largest opera orchestra after the Bavarian State Opera's Bavarian State Orchestra in Munich. Nuremberg is the birthplace of Albrecht Dürer and Johann Pachelbel. Nuremberg was the site of major Nazi rallies, and it provided the site for the Nuremberg trials, which held to account many major Nazi officials.
