That was trespassing on the discoverer’s right to name the planet. So he appended a postscript to the letter to Galle stating that the French Bureau of Longitudes had named the planet Neptune. It was not true. The idea was Le Verrier’s. He may have mentioned it to friends of his at the bureau who unofficially thought the name a good one, but the bureau had no official role in assigning astronomical names. The noun is derived from the proper noun. 2 cognates grc νέφος sa नभस् Pronunciation nĕp′tyo͞on′ RP, en /ˈnɛptjuːn/ /ˈnɛpt͡ʃuːn/ nĕp′to͞on′ GA, en /ˈnɛpˌt(j)un/ en LL-Q1860 (eng)-Naomi Persephone Amethyst (NaomiAmethyst)-Neptune.wav GA /ˈnɛpˌtjun/ en En-us-Neptune.ogg GA /ˈnɛpˌtun/ en /ˈnept͡ʃʉːn/ NZ en neptune en Nep tune Proper noun en Q3954en Roman god The Roman god of earthquakes and the ocean, the counterpart of Poseidon in Greek mythology. en Neptunus Theseus 3 But to returne to Theſeus, Pitheus alſo had geuen it out abroade, that he vvas begotten of Neptune, becauſe the Troezenians haue this god in great veneration, and doe vvorſhippe him as patron and protector of their cittie, making offerings to him of their firſt fruites: and they haue for the marke and ſtampe of their money, the three picked mace, vvhich is the ſigne of Neptune, called his Trident.

The poem likens England’s Parliamentary Navy to Neptune, the god having command over the seas, with the three generals at sea, Richard Deane; George Monck, 1st Duke of Albemarle; and Robert Blake, as the three prongs of Neptune’s trident. What is signified is the English navy’s dominance over the Dutch navy during the First Anglo-Dutch War (1652–1654).

He was wearing a long, pale-green tunic fastened at the waist and in one hand he held what looked like a huge, three-pronged fork. He grinned at the children a little sheepishly.

Leverrier Urbain Le Verrier presented a fifth and final memoir on the new planet, which M. François Arago proposes to be called Neptune. Republished from The Scotsman. 37–38 37 It was on the first day of the new year that the announcement was made, almost simultaneously from three observatories, that the motion of the planet Neptune, the outermost of all the planets that wheel about the sun, had become very erratic. Ogilvy had already called attention to a suspected retardation in its velocity in December. Such a piece of news was scarcely calculated to interest a world the greater portion of whose inhabitants were unaware of the existence of the planet Neptune, nor outside the astronomical profession did the subsequent discovery of a faint remote speck of light in the region of the perturbed planet cause any very great excitement. Scientific people, however, found the intelligence remarkable enough, even before it became known that the new body was rapidly growing larger and brighter, that its motion was quite different from the orderly progress of the planets, and that the deflection of Neptune and its satellite was becoming now of an unprecedented kind. en 1990 Mark Littmann Voyager 2 at Neptune: Beyond Imagination Planets Beyond: Discovering the Outer Solar SystemUpdated and Revised revised New York, N.Y.

But Neptune is too distant for sublight to stir its atmosphere significantly. The temperature is almost unimaginably cold—about -352°F (-214°C, 59°K). Neptune greeted Voyager with a grand variety of clouds, spots, and bands. They must be caused not by the Sun but by Neptune itself—by heat rising from its interior. en 27 June 2024 Zulfikar Abbany Asteroids and Comets: What’s the Difference? w:Deutsche Welle https://web.archive.org/web/20260515110651/https://www.dw.com/en/asteroids-and-comets-whats-the-difference/a-69485128 The duration of planetary orbits ranges widely. Mercury—the closest planet to the sun—has an 88-day orbit, while Earth, the third from the sun, takes 365 days (1 year). Mars needs almost twice that time to fly around the sun, while Saturn takes 10,759 days (29.4 years). Neptune, the furthest planet from the sun, has an orbit of 60,190 days (164.9 years). en place c/USA: en Q2641218 en twp co/Monmouth County s/New Jersey. en Q22134020 en unincorporated community twp/Center Township co/Mercer County s/Ohio. en Q6995621en unincorporated community co/Jackson County s/West Virginia. en Q14714561en unincorporated community town:pref/Ithaca co/Richland County s/Wisconsin.
