Florianópolis vs Sun

Informations

Florianópolis (Portuguese pronunciation: [floɾi.aˈnɔpolis]) is the capital and second largest city of the state of Santa Catarina, in the South region of Brazil. The city encompasses Santa Catarina Island and surrounding small islands, as well as part of the mainland. It has a population of 477,798, according to the 2016 IBGE (Brazilian Institute of Geography and Statistics) population estimate, the second most populous city in the state (after Joinville), and the 47th in Brazil. The metropolitan area has an estimated population of 1,111,702, the 21st largest in the country. The city is known for having the country's third highest Human Development Index score among all Brazilian cities (0.847).The economy of Florianópolis is heavily based on information technology, tourism and services. The city has 60 beaches and is a center of surfing activity. Lagoa da Conceição is the most famous area for tourism, recreation, nature and radical sports. The New York Times reported that "Florianopolis is the Party Destination of the Year in 2009." Newsweek placed Florianópolis in the "Ten most dynamic cities of the world" list in 2006. Veja, a Brazilian publication, named the city as "the best place to live in Brazil.

" As a result of this exposure, Florianópolis is growing as a second home destination for many Paulistas, Argentines, North Americans, and Europeans. Most of the population lives on the mainland and on the island's central and northern parts. The southern half is less inhabited. Many small commercial fishermen populate the island. The fishing boats, the lacemakers, the folklore, the cuisine and the colonial architecture contribute to the growing tourism and attracts resources that compensate for the lack of any large industry. Villages immersed in tradition and history, such as Santo Antônio de Lisboa and Ribeirão da Ilha still resist the advances of modernity.The Hercílio Luz International Airport serves the city. Florianópolis is home to the Universidade Federal de Santa Catarina (Federal University of Santa Catarina). There are also the Santa Catarina Federal Institute of Education, Science and Technology (Instituto Federal de Santa Catarina), and two campuses of the Universidade do Estado de Santa Catarina (State University of Santa Catarina), among other institutions of higher and professional education.

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.
