The axis of the solar system is the sun, which is an average star, and with its very great gravitational force it holds the planets and billions of small celestial bodies, which are generally called secondary bodies. The sun is the closest star to us which allows through its great energy, existence of life on Earth. The light emitted by the sun every second is equal to 3 million billion billion bulbs of 100 watts each and they are responsible for all phenomena. observed in planetary atmospheres. From the deadly sulfuric acid clouds of Venus, to the life-giving terrestrial clouds, right up to the powerful hurricanes of Jupiter and Saturn and the very strong winds of Neptune’s atmosphere. The sun is life itself Solar System. The comparison with the planets is merciless. Even compared to Jupiter, the largest planet in the solar system, with a diameter of 11 times that of the Earth, the Sun is still 10 times larger and 1000 times larger. In fact, the sun contains about 99% of the mass of the entire solar system, giving up only to other inhabitants crumbs of the material from which it was formed.
