Bangui vs Sun

Informations

Bangui (French pronunciation: ​[bɑ̃ɡi]) (or Bangî in Sango, formerly written Bangi in English) is the capital and largest city of the Central African Republic. As of 2012 it had an estimated population of 734,350. It was recognized as a French outpost in 1889 and named after its location on the northern bank of the Ubangi River (French: Oubangui); the Ubangi itself was appointed from the Bobangi word for the"rapids" situated beside the settlement, which marked the end of navigable water north from Brazzaville. The majority of the population of the Central African Republic lives in the western parts of the country, in Bangui and the surrounding region. The city creates an autonomous commune (commune autonome) of the Central African Republic that's surrounded by the Ombella-M'Poko prefecture. Having an area of 67 square kilometres (26 sq mi), the commune is the smallest high-level administrative division in the nation, but the highest in terms of population.

The city consists of eight urban districts (arrondissements), 16 groups (groupements) and 205 neighbourhoods (quartiers). As the capital of the Central African Republic, Bangui acts as an administrative, trade, and industrial centre. It is served with the Bangui M'Poko International Airport. The National Assembly, government buildings, banks, foreign enterprises and embassies, hospitals, hotels, main markets and the Ngaragba Central Prison are located here. Bangui manufactures textiles, food products, beer, shoes and soap. Its Notre-Dame Cathedral is the seat of the Roman Catholic Archdiocese of Bangui. The city is also home to the University of Bangui, inaugurated in 1970. Bangui has been the scene of intense rebel activity and destruction during decades of political upheaval, including the recent rebellion. As a result of political unrest, the city was named in 1996 as one of the most dangerous on earth.

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.
