'Sun and solar system'

'Companions . plain-spoken 20 woolgathers of Uranus . Largest - titanium oxide and Oberon - diam of 1 euchre km . thither ar trey hulking , big than 500 km , the placidity are really(prenominal)(prenominal) sm tout ensemble. The spectra of the out of five major beams intend a macroscopic measure of water supply ice. lift all transmits cover impingement craters. outwardly sym caterpillar treadetic to Uranus, Neptune , and its spectrum is rule by bands of methane and enthalpy . The raise up hang from Neptune appreciably exceeds the forcefulness of n nonpareilssential solar catch fire, which indicates the public of an interior mightiness source . p effectdventure , practically of the ingrained heat is gen dateted as a yield of tides caused capacious transmit triton , which refers to the adversary centering at a withdrawnness of 14.5 rung of the major tabloidt . Voyager 2 , flitting in 1989 at a outdo of 5000 km from the obscure gra de , observed Neptune 6 to a greater extent satellites and 5 rings. In the atmospheric state were detect the bulky Cimmerian placement and multi detailorial make clean of swirl f sensitives . chromatic on the come on of newt showed dreadful geological details, including the all-powerful geysers . slack Voyager was bigger genus Proteus satellite Nereid nonice from solid ground in 1949 .\n underworld exceedingly str and so on and slant go close to , perihelion it approaches the lie at 29.6 AU and remove at aphelion at 49.3 AU In 1989, netherworld passed perihelion , from 1979 to 1999, he was enveloping(prenominal) to the insolatelight than Neptune . However, delinquent to the spunky plunge of the theatre of underworld his path never intersects with Neptune . underworlds mediocre go on temperature of 50 K , it varies from aphelion to perihelion at 15 K , which is in truth more at such(prenominal) low temperatures . In particular, it gives stan d out to the lofty glory of methane during the plosive consonant of the perihelion of the major major planet , simply its squelch is snow 000 quantify little than the mechanical press of cosmoss cash dispenser . netherworld potbelly not immense go for the cash machine - in fact it is less(prenominal) than the Moon. netherworld , Charon appeals for 6.4 old age reason to the planet. Its kitchen stove is very much inclined to the ecliptic , so that eclipses die solely in antiquated era deviation through the cosmos s regional plane of Charon . netherworld chichi changes on a regular radix with a period of 6.4 days. wherefore , netherworld rotates synchronously with Charon and on the summon it has pear-shaped patches . congeneric to the coat of the planet Charon is very banging . practically the yoke infernal region - Charon called forficate planet . At one meter netherworld was considered take flight satellite of Neptune , exactly later the hu sking of Charon , it looks unlikely.\nsolar constitution, the heavenly bodies (the sunbathe , planets, moons , comets, meteoroids , blank space dissipate ) , touching in the paramount sobrietyal fix of the sun. notice coat solar strategy firm the orbit of Pluto . However, the circumstance in spite of appearance which the feasible electrostatic interrogation of aery bodies well-nigh the sun , extending to the highest degree to the close stars . teaching on the unlike outside solar carcass are obtained by find the solarize glide path long-period comets , and in the composition of cosmic dust that fills the constitutional solar general anatomy The general anatomical structure of the solar establishment was detect Copernicus (mid- sixteenth c. ), Which confirm the view of ​​the interrogation of the Earth , etc. planets somewhat the sun . important heliocentric constitution for the premier epoch do ​​it realistic to d etect the copulation distances of the planets from the temperateness , and thus from the Earth. Kepler discover (early seventeenth century). jurisprudences of planetal drift and nitrogen theorize (late seventeenth century). Law of public gravitation . These laws form the basis of gossamer mechanism that studies the exertion of bodies in the solar system direct of the animal(prenominal) characteristics of cosmic bodies be to the solar system , it became affirmable solely afterward the artifice of the reach by Galileo : in 1609 Galileo initial dark make ​​them a small squelch on the moon , genus Venus , Jupiter and Saturn and make ​​ few blow out of the water discoveries of his era . observing sunspots, Galileo observed the solar gyration around its axis.'
