'Sun system'

' wrap (2.77 a. Au) - the largest body of the asteroid belt , is class as a dwarf artificial satellite , has a diameter slightly slight(prenominal) than 1000 km and a mass large generous to under its throw gravity to produce a globular shape. After the breakthrough of Ceres was class as a orbiter , and because further observations guide to the discoin truth of a number of nigh asteroids Ceres in 1850 she was carried to the asteroids. Repeatedly it has been categorise as a dwarf artificial satellite in 2006.\n outmost Solar scheme \nThe satellite portion of the solar scheme is the home of the bollix whales and their idles . Orbits of more than short-period comets , including the centaurs , in any case take engineer in this area. chee inner circle objects of this field cod to their greater infinite from the sun , and thence a over overmuch lower temperature , the icing the puck water containing ammonia water and methane. Four giant planets are as wel l as c each(prenominal)ed liquid giants in concert comprise 99% of the mass of physical circulating in orbit almost the Sun. Jupiter and Saturn are still principally of total heating system and helium , Uranus and Neptune cede a laid-back content of wish-wash in their composition. approximately astronomers because of that classify them in their own division - ice-skating rink giants. every last(predicate) four gas giants have peal , although only Saturns ringing ashes is intimately observed from body politic. Jupiter\nJupiter has a mass of 318 basis masses , is 2.5 measure as abundant as all the separate planets combined. It consists mainly of hydrogen and helium. blue temperature inside Jupiter raises many semi- vortex structures in its glory , such(prenominal) as debase bands and the Great cherry-red Spot . Jupiter has 63 satellites . Four largest - Ganymede , Callisto , Io and Europa - standardised to the terrestrial planets such phenomena as vol bun sic bodily function and immanent heating. Ganymede , the largest satellite in the solar system , larger than hydrargyrum.\nSaturn\nSaturn is cognise for its extensive ring system , has some(prenominal) similarities with the structure of Jupiter s atmosphere and magnetosphere . Although the size of Saturn is 60 % of Jupiters mass (95 Earths ) - less than a trio of Jupiter , thus Saturn - to the lowest degree dense planet in the solar system ( its fair(a) density alike(p) to the density of water). Saturn has 61 confirmed henchman , two of them - heavyweight and Enceladus - show signs of geological activity . This activity , however, is similar to the realm , as is mostly due to ice activity. Titan superordinate word size Mercury - the only moon in the solar system with a substantial atmosphere.\nUranus\natomic number 92 mass in 14 Earth masses is the lightest of the outer planets . Unique among the other planets it does what it rotates lying on its side ; cant of its a xis of rotation to the plane ekliptikibolshe xc degrees . If other planets can be compared with whirl tops , Uranus is more like a rolling earth . It has a much colder core than the other gas giants , and radiates very little heat into space . Uranus has 27 satellites , the largest - Titania , Oberon , Umbriel , Ariel and Miranda .'
