Sun vs Tirana Municipally

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.

Tirana ((listen) Tih-RAH'n@, Albanian pronunciation: [ti’rana]; Gheg Albanian pronunciation: Tirona), is Albania's capital and largest city. It is situated in central Albania, enclosed by mountains and hills. Dajti rises to the east. A slight valley to its northwest overlooks the Adriatic Sea. The city's location on the Plain of Tirana, and its close proximity to the Mediterranean Sea make it a Mediterranean-influenced climate. It has 2,544 hours of sunshine per year and is one of the sunniest and wettest cities in Europe. Since the Iron Age, the area that now corresponds with the city's territory has been continuously inhabited. It was home to Illyrians and was probably the heart of the Illyrian Kingdom, the Taulantii. Classical Antiquity centered it in the hinterland, Epidamnus. It was annexed to Rome by the Illyrian Wars and made an integral part the Roman Empire. The Mosaics from Tirana are a reminder of the rich heritage of that time.

This site was also used as a location for an Early Christian basilica that was constructed in the 5th-6th centuries. The Byzantine Empire, which succeeded the Roman Empire, took control of most of Albania and built Petrele Castle under Justinian I. It was a small city until the Congress of Lushnje declared it Albania's capital in the 20th century. This was after the Albanian Declaration of Independence of 1912. Tirana, a gamma world-city, is the largest economic, financial and political centre in Albania. This is due to its central location and modern air, maritime and rail transportation. It houses the Government of Albania's seat of power, as well as the official residences for the President and Prime Minister of Albania and the Parliament of Albania. It was named the European Youth Capital in 2022.
