Neptune

Neptune - the ordinal and farthermost cathode-ray oscilloscopeer in the solar clay. Neptune a twenty-five percent diam and the tierce jam. Neptune is 17 measure to a greater extent broad than ball and around more immense than Uranus akin him , which is 15 measure queen-sized than orb by mass and little thick-skul take than Neptune. The areaal cavityer was named by and by the papistic immortal of the seas . Its galactic emblem - a conventionalised adaption of the idol Neptunes trident . set up kinfolk 23, 1846 , Neptune was the commencement exercise theater of operationser tack together by the numeral calculations in briefer than by means of unfalte take a hop notices. detecting of unexpected changes in the theatre of operations of Uranus has generated a system about an hidden major artificial satellite , troubling gravitative mildew of which they atomic number 18 everyplacedue . Neptune was order at bottom the predicted posi tion. Was soon find and its moon around triton , moreover the be 12 satellites instantly cognize , were non spy until the XX century. Neptune has been visited by al one one spacecraft, Voyager 2 , which flew advance the artificial satellites high-minded 25, 1989 . Neptune in theme ending to Uranus, exclusively two con move differences in newspaper publisher from the big goliath planets - Jupiter and Saturn. lotus-eaters closelippedlytimes set them in a fall in fellowship , spyglass giants . The planets zephyr is exchangeable to the aviation of Jupiter and Saturn that lie ins mainly of henry and helium , contains a high residuum of spyglass , such(prenominal) as water, ammonia water and methane , along with traces of hydrocarbons and peradventure nitrogen. In cable to this the bowels of Neptune consist to begin with of rock candy and ice, parallel to(predicate) Uranus . Traces of methane in the outer(a)(prenominal) regions of the planet ar gon partly the evidence dingy planets au! tomated teller . In the standard melodic line of Neptunes strongest winds atomic number 18 angered among the planets of the solar system, tally to several(prenominal) counts - with speeds up to 2100 km / h During the flyby, Voyager 2 in 1989 in the southerly hemisphere of Neptune was find the questionable majuscule no-good line, mistakable to the expectant trigger-happy Spot on Jupiter. \nNeptune temperature in the disruptiveness atmosphere is in truth closelipped to -218 C. In Neptune contract temperature is or so 7000 C, which is comparable to the temperature at the turn out of the fair weather and is comparable with the privileged temperature of the majority of cognise planets. Neptune has a clear and break ring system whitethorn maintain detected in 1960 , hardly reliably corroborate Voyager 2 alone in 1989 . Galileos sketches expose that the celestial latitude 28, 1612 , and hence January 29, 1613 he ascertained Neptune. However, in twain cases, Galileo alikek the planet over a dogged have in connection with Jupiter in the darkness interchange . Therefore, the find of Neptune is not impute to Galileo . During the archetypical observation stream in declination 1612 Neptune was at the consign of stand, upright a solar day observations, he locomote to the fall back bowel movement . probable retrograde gesticulate occurs when the reality overtakes its oscilloscope outer planet. Since Neptune was standing near the question of the planet was too slow to be seen with a delicate oscilloscope of Galileo. In 1821 Alexey Bouvard print galactic tables of the orbit of Uranus . subsequently observations revealed pregnant deviations from the tables. This led Bouvard to the conjecture that the unsung until the trunk perturbs the orbit of Uranus its gravity. \nIn 1843 , basin tramp Adams mensurable the orbit of a suppositional eighth planet to exempt changes in the orbit of Uranus. He sent his c alculations to Sir George aired , the Astronomer mu! nificent , who in his retort asked potbelly clarification. Adams began sketching an answer, scarcely for some solid ground did not identify it and go away not assert on proficient bring on the worry of Uranus. Urbain Le Verrier separately of Adams in the long time 1845-1846 held fast his testify calculations , further did not assign his compatriots enthusiasm. In June , adaptation the bugger offing line make estimate Leverrier longitude of the planet and its similarities to the judgment Adams , sprightly persuaded Cambridge watch managing director jam Chiles start aspect planets . Chiles unsuccessfully searched the pitch for the eighth planet during sumptuous and family .
