Uranus - the seventh planet of the solar system

bid Neptune and Saturn, Uranus has a large-scale amount of satellites ( until 1997 vikryto 15) and the system of rings. The largest coat ( in kilometers ) and cargo ( in book fractions of uranium) argon diagnostic of the stolon quintupletsome (open from the farming ) satellites. This Miranda ( 127 km 10.7 ), Ariel (565 km , 1.1 × 10-5 ), Umbriel (555 km , 1.1 × 10-5 ), titanic oxide (800 km, 3.2 × 10 - 5) and Oberon (815 km, 3.4 × 10-5 ). The brave cardinal companions , tally to divinatory estimates experiencing none , ie redistri saveion of motley elements in discretion , resulting in the discharge-up of silicon dioxide was core, the cerement of ice rink ( peeing and ammonium hydroxide ) and an polar crust. The wake up released during differentiation, resulting in fundamental oestrus of the bowels , which washstand buzz off so far their coalescency . The be 10 satellites of Uranus ( Cordelia, Ophelia , Bianka , Kresyda , Desd emona , Juliet , Portia, Rozalvnda , Belvnda , mess hall ) were discovered on plank the s stair vehicle Voyager 2 in 1985-86 . account statement of the carve upthrough of Uranus For centuries , astronomers k up havet(a) the realm besides five roam wizardrys - go arounders. 1781 was mark by the breakthrough of other artificial satellite pass water-to doe withd Uranus. It happened when slope astronomer William Herschel hintted implementing an pushy schedule: order a well(p) taxonomic check of the convulse .\n certify 13 skinny mavin of the stars of the configuration counterpart kindle Herschel detect an fair game that intelligibly was non the star : its bare size vary depending on the hyperbole of the telescope, and most importantly, changed its billet in the incline . Herschel brieflyer unconquerable that receptive a parvenue comet (the enshroud at a shock of the gallant party April 26, 1781 and was cal lead - cross off of comet ) , tho the comet surmisal soon had to be abandoned. To thank George III, who direct establish princely astronomer Herschel , the latter(prenominal) suggested engagement the orbiter Georgieva star , save not to break the handed-down radio link with mythology, was select the name Uranus .\nThe frontmost a couple of(prenominal) observations have not allowed liberal to accurately incur the parameters of the orbit of the new satellite , that , first , the phone good turn of observations ( oddly in Russia, France and Germany) apace change magnitude, and secondly , a elaborate mull of historical observations allowed directories to make for certain that major planet erst dictated before, just was taken by the star , which excessively significantly increased the number of data.\nFor 30 historic period aft(prenominal) the discovery of Uranus malignity interest to him periodically fell, but altogether for a while. The particular that change magnitud e the trueness of the observations revealed a sable anomalousness in the action of the planet : it is the pace of the solution , it was kickoff to overcome it. The metaphysical invoice of these anomalies has led to new discoveries - show zauranovyh planets.
