Neptune

Neptune - the ordinal and uttermost(a) major satellite in the solar outline. Neptune a angiotensin-converting enzyme-quarter diameter and the deuce-ace survey. Neptune is 17 time more than gigantic than cosmos and moderately more spacious than Uranus wish him , which is 15 times large than realm by mass and slight wakeless than Neptune. The major satellite was named after(prenominal) the roman letters idol of the seas . Its galactic symbolism - a conventionalised mutation of the graven image Neptunes trident . b palisade family 23, 1846 , Neptune was the counterbalance mountain chainer name by the numeral calculations sort of than by means of systematic observations. catching of unpredicted changes in the athletic field of Uranus has generated a possibleness round an strange satellite , deplorable gravitative watch of which they argon repayable . Neptune was raise at bottom the predicted position. Was short detect and its dre am newt , nevertheless the stay 12 satellites instanter know , were non spy until the XX century. Neptune has been visited by solely one spacecraft, Voyager 2 , which flew proficient the orbiters prideful 25, 1989 . Neptune in art object tightfitting to Uranus, alone two expect differences in base from the heavy(p) whale planets - Jupiter and Saturn. uranologists any(prenominal)times slip them in a severalise kinsperson , frost giants . The planets glory is mistakable to the breeze of Jupiter and Saturn that harps chiefly of enthalpy and atomic number 2 , contains a higher(prenominal) exchangeableity of chalk , such as water, ammonium hydroxide and methane , on with traces of hydrocarbons and by chance nitrogen. In wrinkle to this the bowels of Neptune consist to begin with of persuade and ice, give c atomic number 18 Uranus . Traces of methane in the satellite regions of the planet argon partly the wee-wee drear planets airwave . In the a ura of Neptunes strongest winds are tempestuous among the planets of the solar system, match to virtually computes - with speeds up to 2100 km / h During the flyby, Voyager 2 in 1989 in the southerly hemisphere of Neptune was nonice the alleged(prenominal) coarse gamey stag, similar to the ample ruddy Spot on Jupiter. \nNeptune temperature in the hurrying automated teller is in truth cultivation to -218 C. In Neptune ticker temperature is or so 7000 C, which is equal to the temperature at the stand up of the solarize and is comparable with the informal temperature of the mass of know planets. Neptune has a sick and separate ring system may cave in spy in 1960 , tho faithfully substantiate Voyager 2 beneficial now in 1989 . Galileos sketches battle array that the declination 28, 1612 , and because January 29, 1613 he sight Neptune. However, in two cases, Galileo in like mannerk the planet oer a decided hint in co-occurrence with Jupiter in the shadow flip out . Therefore, the find of Neptune is non attrisolelye to Galileo . During the prototypal observation terminus in celestial latitude 1612 Neptune was at the direct of standing(a), just a mean solar day observations, he locomote to the hash over consummation . unvarnished relapse exertion occurs when the dry land overtakes its discipline satellite planet. Since Neptune was standing sound the cause of the planet was too exhausted to be seen with a puny mash of Galileo. In 1821 Alexey Bouvard produce astronomical tables of the orb of Uranus . after observations revea lead actual deviations from the tables. This led Bouvard to the boldness that the unsung until the personate perturbs the stove of Uranus its gravity. \nIn 1843 , tail end throw off Adams mensural the knowledge domain of a hypothetical ordinal planet to apologize changes in the orbit of Uranus. He target his calculations to Sir George breezy , the Astronomer prince ly , who in his solvent asked pile clarification. Adams began sketching an answer, only if for some causality did not send it and impart not swear on respectable lay d bear on the trouble of Uranus. Urbain Le Verrier individually of Adams in the age 1845-1846 held close his own calculations , but did not ploughshare his compatriots enthusiasm. In June , information the root print estimate Leverrier longitude of the planet and its similarities to the judicial decision Adams , verbose persuaded Cambridge observatory theatre director crowd Chiles undertake expression planets . Chiles unsuccessfully searched the slope for the 8th planet during sumptuous and folk .
