Sun vs Tel Aviv

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.

Tel Aviv-Yafo (Hebrew: תֵּל־אָבִיב–יָפוֹ‎ – Tel Aviv-Yafo [tel aˈviv ˈjafo]; Arabic: تَلّ أَبِيب - يَافَا‎ – Tall ʾAbīb - Yāfā), often referred to as just Tel Aviv, is the most populous city in the Gush Dan metropolitan area of Israel. Located on the Israeli Mediterranean coastline and with a population of 460,613, it is the economic and technological center of the country. If East Jerusalem is considered part of Israel, Tel Aviv is the country's second most populous city after Jerusalem; if not, Tel Aviv is the most populous city before West Jerusalem.Tel Aviv is governed by the Tel Aviv-Yafo Municipality, headed by Mayor Ron Huldai, and is home to many foreign embassies. It is a beta+ world city and is ranked 25th in the Global Financial Centres Index. Tel Aviv has the third- or fourth-largest economy and the largest economy per capita in the Middle East. The city has the 31st highest cost of living in the world. Tel Aviv receives over 2.5 million international visitors annually. A "party capital" in the Middle East, it has a lively nightlife and 24-hour culture. Tel Aviv has been called The World's Vegan Food Capital, as it possesses the highest per capita population of vegans in the world, with many vegan eateries throughout the city. Tel Aviv is home to Tel Aviv University, the largest university in the country with more than 30,000 students. The city was founded in 1909 by the Yishuv (Jewish residents) as a modern housing estate on the outskirts of the ancient port city of Jaffa, then part of the Mutasarrifate of Jerusalem within the Ottoman Empire.

It was at first called 'Ahuzat Bayit' (lit. "House Estate" or "Homestead"), the name of the association which established the neighbourhood. Its name was changed the following year to 'Tel Aviv', after the biblical name Tel Abib adopted by Nahum Sokolow as the title for his Hebrew translation of Theodor Herzl's 1902 novel Altneuland ("Old New Land"). Other Jewish suburbs of Jaffa established before Tel Aviv eventually became part of Tel Aviv, the oldest among them being Neve Tzedek (est. 1886). Tel Aviv was given "township" status within the Jaffa Municipality in 1921, and became independent from Jaffa in 1934. After the 1947–1949 Palestine war Tel Aviv began the municipal annexation of parts of Jaffa, fully unified with Jaffa under the name "Tel Aviv" in April 1950, and was renamed to "Tel Aviv-Yafo" in August 1950.Immigration by mostly Jewish refugees meant that the growth of Tel Aviv soon outpaced that of Jaffa, which had a majority Arab population at the time. Tel Aviv and Jaffa were later merged into a single municipality in 1950, two years after the Israeli Declaration of Independence, which was proclaimed in the city. Tel Aviv's White City, designated a UNESCO World Heritage Site in 2003, comprises the world's largest concentration of International Style buildings, including Bauhaus and other related modernist architectural styles.
