Sun vs Amiens

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.

Amiens (English or AM-ee-ənz,; French: [amjɛ̃]; Picard: Anmien, Anmiens or Anmyin) is a city and commune in northern France, 120 km (75 mi) north of Paris and 100 km (62 mi) south-west of Lille. It is the capital of the Somme department in Hauts-de-France. The city had a population of 136,105 according to the 2006 census, and has one of the biggest university hospitals in France with a capacity of 1,200 beds. Amiens Cathedral is the largest church in France by volume, estimated at 200,000 cubic metres (260,000 cu yd). It is also a World Heritage Site. The author Jules Verne lived in Amiens from 1871 until his death in 1905, and served on the city council for 15 years. The town was fought over during both World Wars, suffering significant damage, and was repeatedly occupied by both sides. The 1918 Battle of Amiens was the opening phase of the Hundred Days Offensive which directly led to the Armistice with Germany. The Royal Air Force heavily bombed the town during the Second World War. In the aftermath the city was rebuilt according to Pierre Dufau's plans with wider streets to ease traffic congestion. These newer structures were primarily built of brick, concrete and white stone with slate roofs.

The architect Auguste Perret designed the Gare d'Amiens train station and nearby Tour Perret. Amiens has an important historical and cultural heritage, on which a significant amount of tourism is based. Apart from the cathedral, there is the hortillonnages, the Jules Verne House, the Tour Perret, the Musée de Picardie, the zoo, and the quarters of Saint-Leu and Saint-Maurice. A total of 53 monuments are listed in the inventory of monuments historiques, 126 places and monuments listed in the general inventory of cultural heritage, and 263 objects listed in the inventory of monuments historiques. During December, the town hosts the largest Christmas market in northern France. It is known for a few local foods, including "macarons d'Amiens", almond paste biscuits; "tuiles amienoises", chocolate and orange curved biscuits; "pâté de canard d'Amiens", duck pâté in pastry; "la ficelle Picarde", an oven-baked cheese-topped crêpe; and "flamiche aux poireaux", a puff pastry tart made with leeks and cream.
