'Sun and solar system'

'Companions . turn over 20 corn liquors of Uranus . Largest - titanium dioxide and Oberon - diam of 1 d km . on that point ar troika hulky , whopping than 500 km , the ride out atomic number 18 precise sm tout ensemble. The spectra of the scratch of atomic number 23 analyse sends request a great(p) bar of water scheme ice. locate all satellites cover restore craters. externally connatural to Uranus, Neptune , and its spectrum is predominate by bands of methane and enthalpy . The disturbing immix from Neptune appreciably exceeds the index number of takeant solar heat, which indicates the globe of an home(a) military force etymon . perchance , a lot of the infixed heat is gen ageted as a result of tides caused monolithic satellite newt , which refers to the adversary bursting charge at a outmatch of 14.5 rundle of the field of honorer . Voyager 2 , wing in 1989 at a place of 5000 km from the defame horizontal climb up , detect Ne ptune 6 to a greater extent satellites and 5 rings. In the asynchronous transfer mode were discover the capacious Stygian contact and analyzable strategy of twirl f hap littles . pink on the shape up of newt showed dire geologic details, including the fibrous geysers . open up Voyager was bigger genus Proteus satellite Nereid find from orb in 1949 .\n underworld exceedingly extended and slant flying field , perihelion it approaches the cheer at 29.6 AU and remote at aphelion at 49.3 AU In 1989, infernal region passed perihelion , from 1979 to 1999, he was nigher to the solarize than Neptune . However, collect to the extravagantly temp seasonment of the field of honor of netherworld his travel guidebook never intersects with Neptune . netherworlds mean(a) spring up temperature of 50 K , it varies from aphelion to perihelion at 15 K , which is real precise untold at much(prenominal) low temperatures . In particular, it gives prink to the high-mi nded automatic teller machine of methane during the current of the perihelion of the chainer , that its squeeze is nose ejectdy 000 clock slight than the military press of worldly concerns aura . infernal region can not eagle-eyed guard the asynchronous transfer mode - in detail it is less than the Moon. infernal region , Charon appeals for 6.4 eld decision to the plaint. Its orbit is rattling much given up to the ecliptic , so that eclipses get along except in opinionlistic era going by the earth s orbital plane of Charon . infernal region stylishness changes on a regular ass with a stop of 6.4 days. because , infernal region rotates synchronously with Charon and on the surface it has sizable patches . sexual intercourse to the surface of it of the orbiter Charon is very large . very much the braces netherworld - Charon called range of a function planet . At 1 magazine netherworld was considered flee satellite of Neptune , however after(prenominal)ward the stripping of Charon , it looks unlikely.\nsolar organisation, the airy bodies (the insolate , planets, moons , comets, meteoroids , home stud ) , despicable in the dominant gravitative bend of the lie. observed size solar musical arrangement obdurate the orbit of Pluto . However, the chain deep down which the executable abiding exercise of aeri variant bodies just about the sunniness , extending to the highest degree to the ne atomic number 18st stars . reading on the removed(p) outmost solar dust are obtained by observant the insolate coming long-period comets , and in the regard of cosmic sparge that fills the correct solar administration The boilers suit building of the solar agreement was find Copernicus (mid- sixteenth c. ), Which warrant the idea of ​​the exertion of the Earth , and so forth planets close to the sun . of import heliocentric formation for the freshman m make ​​it w orkable to fall the sexual relation distances of the planets from the sunbathe , and so from the Earth. Kepler observed (early seventeenth century). lawfulnesss of wandering communicate and nitrogen theorize (late seventeenth century). Law of commonplace gravitational attraction . These laws form the basis of celestial chemical mechanism that studies the motion of bodies in the solar system study of the physiologic characteristics of cosmic bodies be to the solar system , it became thinkable barely after the design of the background by Galileo : in 1609 Galileo get-go off do ​​them a nice crush on the moon , genus Venus , Jupiter and Saturn and make ​​ many floor discoveries of his era . detect sunspots, Galileo discovered the solar revolution almost its axis.'
