Kuala Lumpur vs Sun

Informations

Kuala Lumpur (Malaysian pronunciation: [ˈkualə, -a ˈlumpo(r), -ʊ(r)]), officially the Federal Territory of Kuala Lumpur (Malay: Wilayah Persekutuan Kuala Lumpur) and colloquially referred to as KL, is a federal territory and the capital city of Malaysia. It is the largest city in Malaysia, covering an area of 243 km2 (94 sq mi) with an estimated population of 1.73 million as of 2016. Greater Kuala Lumpur, also known as the Klang Valley, is an urban agglomeration of 7.564 million people as of 2018. It is among the fastest growing metropolitan regions in Southeast Asia, in both population and economic development. Kuala Lumpur is the cultural, financial and economic centre of Malaysia. It is also home to the Parliament of Malaysia and the official residence of the Yang di-Pertuan Agong, the Istana Negara. It first developed as a town serving the tin mines of the region circa 1857, before it became the capital of Selangor in 1880 until 1978, and the capital of Malaya before the formation of Malaysia. The city remained the seat of the executive and judicial branches of the federal government until these were relocated to Putrajaya in early 1999.

However, some sections of the political bodies still remain in Kuala Lumpur. Kuala Lumpur is one of the three federal territories of Malaysia, enclaved within the state of Selangor, on the central west coast of Peninsular Malaysia. Since the 1990s, the city has played host to many international sporting, political and cultural events including the 1998 Commonwealth Games and the 2017 Southeast Asian Games. Kuala Lumpur has undergone rapid development in recent decades and is home to the tallest twin buildings in the world, the Petronas Towers, which have since become an iconic symbol of Malaysia in general. Kuala Lumpur has a comprehensive road system supported by an extensive range of public transport networks, known as the Klang Valley Integrated Transit System. It was ranked as being the 6th most-visited city in the world in 2019 by Mastercard. The city houses three of the world's 10 largest shopping malls. In 2020, Kuala Lumpur was named as the World Book Capital by UNESCO.

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.
