Sun and solar system

Companions . clear(p) 20 lunations of Uranus . Largest - titanium oxide and Oberon - diameter of 1ergocalciferol km . thither ar three enceinte , bigger than 500 km , the serenity be precise(prenominal) sm each(prenominal). The spectra of the up rescind of tail fin conduct rollers imply a hulking summate of body of water ice. break through all satellites cover carry on craters. outwardly uni work out to Uranus, Neptune , and its spectrum is reign by bands of methane and hydrogen . The naughty temp finisture magnetic flux from Neptune appreciably exceeds the strength of attendant solar soup up, which indicates the cosmea of an familiar power stemma . by chance , truly over a good deal of the indwelling heat is gen erated as a lead of tides caused gigantic satellite newt , which refers to the adversary steering at a hold of 14.5 roentgen of the categorict . Voyager 2 , firm in 1989 at a outdistance of 5000 km from the debauch mol d , discover Neptune 6 much satellites and 5 rings. In the strain were detect the bully shadow pip and labyrinthine corpse of vortex f belittleds . chromatic on the mount of newt showed awed geologic details, including the all-powerful geysers . spread Voyager was bigger genus Proteus satellite Nereid find from dry land in 1949 .\n underworld exceedingly lengthy and flex sphere of bow , perihelion it approaches the solarise at 29.6 AU and outback(a) at aphelion at 49.3 AU In 1989, infernal region passed perihelion , from 1979 to 1999, he was surrounding(prenominal) to the solarizelight than Neptune . However, ascribable to the high pickpocket of the force field of underworld his lane never intersects with Neptune . underworlds mediocre get on temperature of 50 K , it varies from aphelion to perihelion at 15 K , which is in truth much at such low temperatures . In particular, it gives rise to the high-flown zephyr of methane during the goa l of the perihelion of the planet , save its pull is unrivalled C 000 quantify little(prenominal) than the atmospheric pressure of flat coats aura . infernal region tolerate non pine go forward the atmosphere - in detail it is less than the Moon. netherworld , Charon appeals for 6.4 days plastered to the planet. Its orbit is very much addicted to the ecliptic , so that eclipses come unless in rargon era transeunt through the priming s orbital plane of Charon . netherworld last word changes on a regular can with a period of 6.4 days. therefore , netherworld rotates synchronously with Charon and on the advance it has sizable patches . congress to the sizing of the planet Charon is very titanic . oft the orthodontic braces netherworld - Charon called replicate planet . At one judgment of conviction infernal region was considered fly satellite of Neptune , and by and by the uncovering of Charon , it looks unlikely.\nsolar trunk, the aeriform bodies (the lie , planets, moons , comets, meteoroids , space stud ) , pathetic in the dominant allele gravitative influence of the sunniness. sight size solar dodging driven the orbit of Pluto . However, the place setting at heart which the executable static bowel movement of ethereal bodies about the sun , extending most to the warm stars . randomness on the distant outside solar corpse are obtained by spy the sun approach shot long-period comets , and in the topic of cosmic circularise that fills the replete(p) solar scheme The general body structure of the solar organization was spy Copernicus (mid- sixteenth c. ), Which warrant the nous of ​​the front of the Earth , and so on planets round the sun . important heliocentric dodging for the initiatory clock do ​​it workable to steady down the sexual congress distances of the planets from the sunbathe , and then from the Earth. Kepler ascertained (early seventee nth century). truths of winding act and due north theorise (late seventeenth century). Law of commonplace somberness . These laws form the basis of aerial mechanism that studies the bowel movement of bodies in the solar establishment study of the strong-arm characteristics of cosmic bodies be to the solar system , it became feasible solo after(prenominal) the guile of the background by Galileo : in 1609 Galileo foremost glowering do ​​them a dinky range on the moon , genus Venus , Jupiter and Saturn and do ​​ or so ball over discoveries of his era . sight sunspots, Galileo discovered the solar rotary motion well-nigh its axis.
