Brooklyn vs Sun

Informations

Brooklyn () is a borough of New York City, coterminous with Kings County, in the U.S. state of New York. It is the most-populous county in the state, the second-most densely populated county in the United States, and New York City's most populous borough, with an estimated 2,648,403 residents in 2020. Named after the Dutch village of Breukelen, it shares a land border with the borough of Queens at the western end of Long Island. Brooklyn has several bridge and tunnel connections to the borough of Manhattan across the East River, and the Verrazzano-Narrows Bridge connects it with Staten Island. With a land area of 70.82 square miles (183.4 km2) and water area of 26 square miles (67 km2), Kings County is New York state's fourth-smallest county by land area and third-smallest by total area, though it is the second-largest among the city's five boroughs in terms of area and largest in terms of population. If each borough were ranked as a city, Brooklyn would rank as the third-most populous in the U.S., after Los Angeles and Chicago. Brooklyn was an independent incorporated city (and previously an authorized village and town within the provisions of the New York State Constitution) until January 1, 1898, when, after a long political campaign and public relations battle during the 1890s, according to the new Municipal Charter of "Greater New York", Brooklyn was consolidated with other cities, towns, and counties to form the modern City of New York, surrounding the Upper New York Bay with five constituent boroughs.

The borough continues, however, to maintain a distinct culture. Many Brooklyn neighborhoods are ethnic enclaves. Brooklyn's official motto, displayed on the Borough seal and flag, is Eendraght Maeckt Maght, which translates from early modern Dutch as "Unity makes strength". In the first decades of the 21st century, Brooklyn has experienced a renaissance as an avant-garde destination for hipsters, with concomitant gentrification, dramatic house price increases and a decrease in housing affordability. Since the 2010s, Brooklyn has evolved into a thriving hub of entrepreneurship, high technology startup firms, postmodern art and design.

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.
