The Sun is 1.4 million kilometers (4.643 light-seconds) wide, about 109 times wider than Earth, or four times the Lunar distance, and contains 99.86% of all Solar System mass. The Sun is a G-type main-sequence star that makes up about 99.86% of the mass of the Solar System. [26]
If the Sun–Neptune distance is scaled to 100 metres (330 ft), then the Sun would be about 3 cm (1.2 in) in diameter (roughly two-thirds the diameter of a golf ball), the giant planets would be all smaller than about 3 mm (0.12 in), and Earth's diameter along with that of the other terrestrial planets would be smaller than a flea (0.3 mm or 0. ...
The Sun has also undergone periodic changes in luminosity that can have a significant impact on the Earth. [108] The Maunder minimum, for example, is believed to have caused the Little Ice Age phenomenon during the Middle Ages. [109] At the center of the Sun is the core region, a volume of sufficient temperature and pressure for nuclear fusion ...

In the spectral class label, G2 indicates its surface temperature, of approximately 5770 K ( the UAI will accept in 2014 5772 K) and V indicates that the Sun, like most stars, is a main-sequence star, and thus generates its energy via fusing hydrogen into helium. In its core, the Sun fuses about 620 million metric tons of hydrogen each second.
As of 2005 the star with the lowest iron content ever measured is the dwarf HE1327-2326, with only 1/200,000th the iron content of the Sun. [134] By contrast, the super-metal-rich star μ Leonis has nearly double the abundance of iron as the Sun, while the planet-bearing star 14 Herculis has nearly triple the iron. [135]
Among the archaic solar myths are myths about the emergence of the Sun and the destruction of superfluous suns, about the disappearance and return of the Sun, common among African, Siberian, and Australian peoples. As Vyacheslav Ivanov suggests, twin myths about the Sun and the Moon and the motif of the “heavenly wedding” also seem archaic ...
