Santo Domingo vs Sun

Informations

Santo Domingo (Spanish pronunciation: [ˈsanto ðoˈmiŋɡo] meaning "Saint Dominic"), once known as Santo Domingo de Guzmán, is the capital and largest city of the Dominican Republic and the largest metropolitan area in the Caribbean by population. As of 2010, the city had a total population of 2,908,607, when including the metropolitan area. The city is coterminous with the boundaries of the Distrito Nacional ("D.N.", "National District"), itself bordered on three sides by Santo Domingo Province. Founded by the Spanish in 1496, on the east bank of the Ozama River and then moved by Nicolás de Ovando in 1502 to the west bank of the river, the city is the oldest continuously inhabited European settlement in the Americas, and was the first seat of the Spanish colonial rule in the New World. Santo Domingo is the site of the first university, cathedral, castle, monastery, and fortress in the New World.

The city's Colonial Zone was declared as a World Heritage Site by UNESCO. Santo Domingo was called Ciudad Trujillo (Spanish pronunciation: [sjuˈðað tɾuˈxiʝo]), from 1936 to 1961, after the Dominican Republic's dictator, Rafael Trujillo, named the capital after himself. Following his assassination, the city resumed its original designation. Santo Domingo is the cultural, financial, political, commercial and industrial center of the Dominican Republic, with the country's most important industries being located within the city. Santo Domingo also serves as the chief seaport of the country. The city's harbor at the mouth of the Ozama River accommodates the largest vessels, and the port handles both heavy passenger and freight traffic. Temperatures are high year round, with cooler breezes during winter time.

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.
