Aden City vs Sun

Informations

Aden is the UK's AY-d@n and US's AH-den. It is located near the Red Sea (the Gulf of Aden) at 170 km (110 miles) east of Bab-el-Mandeb. The city is home to approximately 800,000. Aden's natural harbour is located in the crater a dormant volcano. It now forms a peninsula that connects to the mainland via a low isthmus. Front Bay was the first harbour to be used by the ancient Kingdom, Awsan, between the 7th and 5th centuries BC. On the opposite side of the peninsula is the modern harbour. The Gulf of Aden is named after Aden. Aden is made up of several sub-centres. Crater was the original port city. Maalla was the modern port. Tawahi, also known as Steamer Point during colonial times, and the resorts at Gold Mohur are all part of the main centre. Khormaksar is located on the isthmus connecting Aden with the mainland. It houses the city's diplomatic missions and the main offices for Aden University. Aden International Airport, which was formerly the British Royal Air Force station RAF Khormaksar (Yemens second largest airport), is also here. The sub-centres and Al-Mansura are located on the mainland. These were once an oasis area. Madinat ash-Shab, formerly Madinat al-Itihad, is now the capital of South Arabian Federation. It also houses Aden University's large power/desalinization plant and additional faculties. Aden surrounds the eastern end of the vast, natural harbour that forms the modern port. This made it necessary to create the Cisterns at Tawila, Aden's reservoirs.

According to Ibn Battuta (14th-century scholar), these reservoirs store rainwater solely for the purpose of drinking by the citizens. It is a prosperous city with many wealthy merchants and Indian ships arriving to trade. The port and harbour on the west side are enclosed by the volcanic peninsula of Little Aden. Little Aden was the location of the oil refinery, and the tanker port. They were both established by British Petroleum and were operated until 1978 when they were handed over to the Yemeni government. Aden was the capital of Peoples Democratic Republic of Yemen from 1990 to its unification with Yemen Arab Republic. It briefly served again as Yemen's temporary capital after the Houthi takeover of Yemen. This was declared by President Abd Rabbuh Mansur Hadi following his escape from the Houthi occupation of Sanaa. The Battle of Aden was fought between President Hadi's government forces and the Houthis from March 2015 to July 2015. The city was short of water, food, and medical supplies. The Saudi Army launched an offensive on 14 July to retake Aden in support of the Yemeni government. The Houthis were expelled from Aden within three days. The Southern Transitional Council has seized Aden since February 2018. Supported by UAE, the Southern Transitional Council has taken control of Aden. Former Mayor Aidroos Alzubaidi was fired by Abdrabbuh Mansur Hadi and sacked ex-Minister Salfi-religious leader Hani Bin Buraik.

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.
