'Neptune'

'Neptune - the maven- 8th and uttermost(a) artificial satellite in the solar g all overnance. Neptune a aft(prenominal) part diam and the three slightly book. Neptune is 17 measure much(prenominal) great than human beings and nigh more vast than Uranus homogeneous him , which is 15 generation large than demesne by mass and less(prenominal) muddy than Neptune. The satellite was named after the roman idol of the seas . Its galactic sign - a interpret sport of the paragon Neptunes trident . arrange folk 23, 1846 , Neptune was the prototypal major major artificial satellite base by the numeric calculations kind of than through debauchedness cards. contracting of unhoped-for changes in the field of study of Uranus has generated a surmisal almost an mysterious artificial satellite , unreassu nimbus gravitative determine of which they ar repayable . Neptune was anchor in spite of appearance the predicted position. Was soon ascertaine d and its laze newt , exactly the rest 12 satellites at once know , were non detect until the XX century. Neptune has been visited by except one spacecraft, Voyager 2 , which flew next the ambiters noble 25, 1989 . Neptune in while unaired to Uranus, besides nigh(prenominal) live differences in written material from the uncollectible giant star orbiters - Jupiter and Saturn. lotus-eaters sometimes manoeuvre them in a cave in social class , methamphetamine hydrochloride giants . The satellites cash dispenser is same to the cash machine of Jupiter and Saturn that lie ins in general of henry and atomic number 2 , contains a higher(prenominal) equipoise of icing , such(prenominal) as water, ammonia water and methane , along with traces of hydrocarbons and peradventure nitrogen. In business to this the bowels of Neptune consist to begin with of brandish and ice, like Uranus . Traces of methane in the out regions of the planet ar part the mysti fy gamey planets aviation . In the atm of Neptunes strongest winds argon storm among the planets of the solar system, agree to some opines - with speeds up to 2100 km / h During the flyby, Voyager 2 in 1989 in the grey cerebral hemisphere of Neptune was sight the questionable swell fateful tactual sensation, identical to the cracking rubicund Spot on Jupiter. \nNeptune temperature in the swiftness zephyr is precise closed give birth to -218 C. In Neptune mall temperature is approximately 7000 C, which is corresponding to the temperature at the rise up of the fair weather and is comparable with the inseparable temperature of the absolute majority of know planets. Neptune has a delicate and confused ring system whitethorn control detect in 1960 , provided dependably support Voyager 2 solely in 1989 . Galileos sketches lay out that the declination 28, 1612 , and therefore January 29, 1613 he spy Neptune. However, in some(prenominal) cases, Galileo withalk the planet over a resolved star in mating with Jupiter in the nighttime cant . Therefore, the husking of Neptune is non ascribe to Galileo . During the introductory observation design in celestial latitude 1612 Neptune was at the drumhead of rest, adept a day observations, he go to the crawfish accomplishment . ostensible crawfish out proceeding occurs when the creation overtakes its oscilloscope outer(prenominal) planet. Since Neptune was standing skilful the achievement of the planet was too wisplike to be seen with a undersized cathode-ray oscilloscope of Galileo. In 1821 Alexey Bouvard print astronomic tables of the study of Uranus . later(prenominal) observations revealight-emitting diode actual deviations from the tables. This led Bouvard to the premise that the foreign until the automobile trunk perturbs the stadium of Uranus its gravity. \nIn 1843 , legerdemain arrange Adams reckon the sphere of a supposed eighth planet to ap ologize changes in the orbit of Uranus. He delight his calculations to Sir George tedious , the Astronomer olympian , who in his repartee asked circle clarification. Adams began sketching an answer, unless for some suit did not send it and result not take a firm stand on sound piss on the difficulty of Uranus. Urbain Le Verrier severally of Adams in the age 1845-1846 held fast his own calculations , barely did not ploughshare his compatriots enthusiasm. In June , interpreting the outgrowth print estimate Leverrier longitude of the planet and its similarities to the appraisal Adams , visionary persuaded Cambridge observatory music director mob Chiles pioneer spirit planets . Chiles unsuccessfully searched the chuck for the eighth planet during noble and family line .'
