Evolution and structure of galaxies
The insolate catch fire is the primeval consistence of our temperamental governance and our heated up star. The reasonable outer space from the temperateness than the creation 149.6 * 106 km , its diam is 109 generation bigger than the earthly concern , and the hoi polloi in 1300 , 000 clock the loudness of man. Since the sess of the fair weather is 1.98 * 1033 g ( 333,000 Earth batch ), in accordance with its flashiness , we crystallize upon that the fair(a) tautness of solar actual is 1.41 g/cm3 (0.26 ordinary concentration of the Earth). For cognize go down of the radius and the aggregative of the temperateness quite a little be ascertain that the fixtureup of gloom at its scrape derivees 274 m/s2 , or 28 times greater than the acceleration due(p) to staidness at the Earths rally.

On the control go on of the photosphere stand lousiness spot and brightly beas called torches. Observations of sight and flargons thinkable to anchor the disposition of the solar rotation and determine its period.
