Freebase

  1. Neptune

    Neptune is the eighth and farthest planet from the Sun in the Solar System. It is the fourth-largest planet by diameter and the third-largest by mass. Among the gaseous planets in the solar system, Neptune is the most dense. Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth but not as dense. On average, Neptune orbits the Sun at a distance of 30.1 AU, approximately 30 times the Earth–Sun distance. Named for the Roman god of the sea, its astronomical symbol is ♆, a stylised version of the god Neptune's trident. Neptune was the first planet found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed on 23 September 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier, and its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining 12 moons were located telescopically until the 20th century. Neptune has been visited by only one spacecraft, Voyager 2, which flew by the planet on 25 August 1989.

  2. Neptune

    the remotest planet of the solar system at present known; it is twice as far distant from the sun as Uranus (q. v.) is, deemed before its discovery the remotest; its diameter is four times greater than that of the earth, and it takes 60,126 days to revolve round the sun, accompanied by a solitary satellite; it was discovered in 1846 by Adams (q. v.) and Leverrier (q. v.), who were guided to the spot where they found it from the effect of its neighbourhood on the movements of Uranus.

U.S. National Library of Medicine

Dictionary of Nautical Terms

  1. neptune

    A superior planet, recently discovered; it is the most distant member of the solar system yet known, and was revealed by the effect which its attraction had produced upon the movements of Uranus; this was one of the most admirable solutions in modern mathematical science. Neptune, so far as is yet known, has no satellites.

Examples of Neptune in a Sentence

  1. Grant Govertsen:

    While we do not believe Neptune is leaving the Macau scene we do believe that more junket closures are likely and that liquidity could increasingly become a concern that could drive further downside to the VIP story.

  2. Tomoyuki Kudo:

    Some studies suggested the radius of the ring is about where [our] solar systems asteroid belt would be. Other observations put the size out where Neptune would be, our ALMA observations provided a clear answer: Both are right.

  3. Suzanne Dodd:

    We need to develop an orbiter for each of those planets, at Uranus, the five major moons are very different. They have unique geological history, so we need to understand how they were formed or captured. Uranus has a rotational pole that is tipped on its side more than the Earth, so we need an understanding of why that happened. At Neptune, there are a great amount of features in atmosphere similar to Jupiter and Saturn. And Neptune's moon Triton is of interest because of the methane geysers on it.

  4. Karl Mitchell:

    Triton is weird, but yet relevantly weird, because of the science we can do there, we know the surface has all these features weve never seen before, which motivates us to want to know How does this world work ?

  5. Joanna Barstow:

    Gliese 1214 b is a type of planet we call a Super-Earth -- a bit bigger than Earth, a bit smaller than Neptune. It's not dense enough to be rocky so it's probably like a warm mini-Neptune. There's nothing like it in our solar system and we don't really know what to expect, on my wish list for the future is a telescope to study exoplanets like Gliese 1214 b in more detail. I want to know what's going on beneath that cloud layer !
