Sun vs Santa

Informations

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.

Santa Claus, also known as Father Christmas, Saint Nicholas, Saint Nick, Kris Kringle, or simply Santa, is a character from legends originating in Western Christian culture who is said to bring gifts on Christmas Eve to well-behaved children or coal for naughty children. The modern character of Santa Claus was based on traditions surrounding the historical Saint Nicholas (a fourth-century Greek bishop and gift-giver of Myra), the British figure of Father Christmas, and the Dutch figure of Sinterklaas (also based on Saint Nicholas). Like other gift-bearing figures of the season, Santa Claus also absorbed elements of the Germanic deity Wodan, who was associated with the pagan midwinter event of Yule and led the Wild Hunt through the sky. Santa Claus is generally depicted as a portly, jolly, white-bearded man, often with spectacles, wearing a red coat with white fur collar and cuffs, white-fur-cuffed red trousers, red hat with white fur, and black leather belt and boot, carrying a bag full of gifts for children. This image became popular in the United States and Canada in the 19th century due to the significant influence of the 1823 poem "A Visit from St.

Nicholas." Caricaturist and political cartoonist Thomas Nast also played a role in the creation of Santa's image. This image has been maintained and reinforced through song, radio, television, children's books, films, and advertising. In modern folklore, Santa Claus is said to make lists of children throughout the world. He categorizes them according to their behavior. He then sets out to deliver presents, including toys and candy, to all of the well-behaved children in the world. Misbehaving children receive coal on the night of Christmas Eve. Santa Claus is said to accomplish this feat with the aid of his elves, who make the toys in his workshop at the North Pole. Santa Claus's flying reindeer are also said to provide assistance with pulling his sleigh. He is commonly portrayed as living at the North Pole, and laughing in a way that sounds like "ho ho ho".
