Valencia vs Sun

Informations

Valencia (Spanish: [baˈlenθja]), officially València (Valencian: [vaˈlensia]), is the capital of the autonomous community of Valencia and the third-largest city in Spain after Madrid and Barcelona, surpassing 800,000 inhabitants in the municipality. The wider urban area also comprising the neighbouring municipalities has a population of around 1.6 million. Valencia is Spain's third-largest metropolitan area, with a population ranging from 1.7 to 2.5 million depending on how the metropolitan area is defined. The Port of Valencia is the 5th-busiest container port in Europe and the busiest container port on the Mediterranean Sea. The city is ranked as a Gamma-level global city by the Globalization and World Cities Research Network.Valencia was founded as a Roman colony by the consul Decimus Junius Brutus Callaicus in 138 BC and called Valentia Edetanorum. In 714, Moroccan and Arab Moors occupied the city, introducing their language, religion and customs; they implemented improved irrigation systems and the cultivation of new crops as well. Valencia was the capital of the Taifa of Valencia. In 1238 the Christian king James I of Aragon conquered the city and divided the land among the nobles who helped him conquer it, as witnessed in the Llibre del Repartiment.

He also created the new Kingdom of Valencia, which had its own laws (Furs), with Valencia as its main city and capital. In the 18th century Philip V of Spain abolished the privileges as punishment to the kingdom of Valencia for aligning with the Habsburg side in the War of the Spanish Succession. Valencia was the capital of Spain when Joseph Bonaparte moved the Court there in the summer of 1812. It also served as the capital between 1936 and 1937, during the Second Spanish Republic. The city is situated on the banks of the Turia, on the east coast of the Iberian Peninsula, fronting the Gulf of Valencia on the Mediterranean Sea. Its historic centre is one of the largest in Spain, with approximately 169 ha (420 acres). Due to its long history, Valencia has numerous celebrations and traditions, such as the Fallas, which were declared Fiestas of National Tourist Interest of Spain in 1965 and an Intangible cultural heritage by UNESCO in November 2016. Joan Ribó from Compromís has been the mayor of the city since 2015.

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.
