Bishkek vs Sun

Informations

Bishkek (Kyrgyz: Бишкек, Bişkek, بىشکەک, IPA: [biʃˈkek], Kazakh: Бішкек), formerly Pishpek and Frunze (Russian: Фрунзе), is the capital and largest city of Kyrgyzstan (Kyrgyz Republic). Bishkek is also the administrative centre of the Chuy Region. The state surrounds the city, even though the city itself is not part of the state, but instead a province-level unit of Kyrgyzstan. It's also near the Kazakhstan-Kyrgyzstan border. In 1825, the Khanate of Kokand established the fortress of"Pishpek" to restrain local caravan routes and also to collect tribute from Kyrgyz tribes. On 4 September 1860, with the approval of the Kyrgyz, Russian forces led by Colonel Apollon Zimmermann destroyed the fortress. In 1868, a Russian settlement was established on the website of the fortress under its original title,"Pishpek". It lay within the General Governorship of Russian Turkestan and its Semirechye Oblast. In 1925, the Kara-Kirghiz Autonomous Oblast was established in Russian Turkestan, encouraging Pishpek to its own capital. In 1926, the Communist Party of the Soviet Union renamed the city as Frunze, after the Bolshevik military leader Mikhail Frunze (1885--1925), who was born there.

In 1936, the city of Frunze became the capital of the Kirghiz Soviet Socialist Republic, during the closing stages of the national delimitation in the Soviet Union. In 1991, the Kyrgyz parliament changed the capital's title to"Bishkek". Bishkek is located at an altitude of about 800 metres (2,600 ft), just off the northern fringe of the Kyrgyz Ala-Too Range, an expansion of the Tian Shan mountain range. These mountains rise to a height of 4,895 metres (16,060 ft). North of the city, a fertile and gently undulating steppe extends far north into neighbouring Kazakhstan. The Chui River drains the majority of the region. Bishkek is connected to the Turkestan--Siberia Railway by a spur line. Bishkek is a city of wide boulevards and marble-faced public buildings together with numerous Soviet-style apartment blocks surrounding interior courtyards. Additionally, there are thousands of smaller privately built houses, mostly away from the city centre. Streets follow a grid pattern, with most flanked on both sides by narrow irrigation channels, watering innumerable trees to provide shade in the hot summers.

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.
