Sun vs Ares

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.

Ares (; Ancient Greek: Ἄρης, Áres [árɛːs]) is the Greek god of courage and war. He is one of the Twelve Olympians, and the son of Zeus and Hera. In Greek literature, he often represents the physical or violent and untamed aspect of war and is the personification of sheer brutality and bloodlust, in contrast to his sister, the armored Athena, whose functions as a goddess of intelligence include military strategy and generalship.The Greeks were ambivalent toward Ares: although he embodied the physical valor necessary for success in war, he was a dangerous force, "overwhelming, insatiable in battle, destructive, and man-slaughtering." His sons Phobos (Fear) and Deimos (Terror) and his lover, or sister, Enyo (Discord) accompanied him on his war chariot. In the Iliad, his father Zeus tells him that he is the god most hateful to him. An association with Ares endows places and objects with a savage, dangerous, or militarized quality. His value as a war god is placed in doubt: during the Trojan War, Ares was on the losing side, while Athena, often depicted in Greek art as holding Nike (Victory) in her hand, favoured the triumphant Greeks.

Ares plays a relatively limited role in Greek mythology as represented in literary narratives, though his numerous love affairs and abundant offspring are often alluded to. When Ares does appear in myths, he typically faces humiliation. He is well known as the lover of Aphrodite, the goddess of love, who was married to Hephaestus, god of craftsmanship. The most famous story related to Ares and Aphrodite shows them exposed to ridicule through the wronged husband's device.The counterpart of Ares among the Roman gods is Mars, who as a father of the Roman people was given a more important and dignified place in ancient Roman religion as a guardian deity. During the Hellenization of Latin literature, the myths of Ares were reinterpreted by Roman writers under the name of Mars. Greek writers under Roman rule also recorded cult practices and beliefs pertaining to Mars under the name of Ares. Thus in the classical tradition of later Western art and literature, the mythology of the two figures later became virtually indistinguishable.
