Singapore vs Sun

Informations

Singapore ( (listen)), officially the Republic of Singapore, is a sovereign island city-state in maritime Southeast Asia. It lies about one degree of latitude (137 kilometres or 85 miles) north of the equator, off the southern tip of the Malay Peninsula, bordering the Straits of Malacca to the west, the Riau Islands to the south, and the South China Sea to the east. The country's territory is composed of one main island, 63 satellite islands and islets, and one outlying islet, the combined area of which has increased by 25% since the country's independence as a result of extensive land reclamation projects. It has the second greatest population density in the world. The country is home to almost 5.7 million residents, 61% (3.4 million) of whom are Singaporean citizens. There are four official languages of Singapore: English, Malay, Chinese, and Tamil; with English being the lingua franca. Multiracialism is enshrined in the constitution, and continues to shape national policies in education, housing, and politics. Although its history stretches back millennia, modern Singapore was founded in 1819 by Sir Stamford Raffles as a trading post of the British Empire. In 1867, the colonies in East Asia were reorganised and Singapore came under the direct control of Britain as part of the Straits Settlements. During the Second World War, Singapore was occupied by Japan in 1942, but returned to British control as a separate crown colony following Japan's surrender in 1945. Singapore gained self-governance in 1959, and in 1963 became part of the new federation of Malaysia, alongside Malaya, North Borneo, and Sarawak. Ideological differences led to Singapore being expelled from the federation two years later, thereby becoming an independent country. Since then, Singapore is considered the only fully sovereign city-state in the world, with its own currency and technologically advanced military forces. After early years of turbulence and despite lacking natural resources and a hinterland, the nation rapidly developed to become one of the Four Asian Tigers based on external trade, becoming the highest developed country in Asia.

It has the 2nd-highest GDP per capita in the world and rank 9th on the UN Human Development Index. Singapore is the only country in Asia with an AAA sovereign rating from all major rating agencies. It has been ranked by the World Economic Forum as the world's most competitive in addition to being the freest economy, and the ease of doing business index had ranked Singapore as the easiest place to do business for the past decade. It is a global financial and shipping hub, consistently ranked the most expensive city to live in since 2013, and has been identified as a tax haven. Singapore is placed highly in key social indicators: education, healthcare, quality of life, prosperity, personal safety and housing, with a home-ownership rate of 91%. Singaporeans enjoy one of the world's longest life expectancies, fastest Internet connection speeds and one of the lowest infant mortality rates. Singapore is a unitary parliamentary republic with a Westminster system of unicameral parliamentary government. Singapore is widely regarded to have an incorrupt and meritocratic government, with a fair judiciary and strong rule of law. While the country practices parliamentary democracy, the government has significant control over politics and society, and the People's Action Party has ruled continuously since independence. One of the five founding members of ASEAN, Singapore is also the headquarters of the Asia-Pacific Economic Cooperation (APEC) Secretariat and Pacific Economic Cooperation Council (PECC) Secretariat, as well as many international conferences and events. Singapore was the host to the inaugural Youth Olympic Games in 2010, the Ma–Xi meeting and the 2018 North Korea–United States Singapore Summit. Singapore is also a member of the United Nations, World Trade Organization, East Asia Summit, Non-Aligned Movement and the Commonwealth of Nations.

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.
