List of Neptune's moons List of Neptune's moons. Neptune has a total of 14 moons. The largest moon is Triton which was discovered by William Lassell just seventeen days after Neptune was found. Then it took one hundred years later to find the second moon, Nereid. The Hubble Telescope found the 14th moon in 2013.

How Many Moons Does Neptune Have? This means that all of the moons on Neptune are smaller than the moon on Earth. Since the 14th moon is a relatively recent discovery, scientists believe that there could be more out there that have yet to be discovered. You can see that Neptune certainly has many moons and all of them are different in their own way.

How many moons does Saturn have? Both Voyager, and later the Cassini probes, have as of 2014, brought the total number of moons of Saturn to 62. Of those, 53 have official names whilst the other nine are still being studied. Such is the dynamism of Saturn's orbital environment that this number may change again in the future.

Planet Neptune: Facts About Its Orbit, Moons & Rings Every 248 years, Pluto moves inside Neptune's orbit for 20 years or so, during which time it is closer to the sun than Neptune. Nevertheless, Neptune remains the farthest planet from the sun, since Pluto was reclassified as a dwarf planet in 2006.eptune's moons. Neptune has 14 known moons, named after lesser sea gods and nymphs from Greek mythology. The largest by far is Triton, whose discovery on Oct. 10, 1846, was in a sense enabled by beer — amateur astronomer William Lassell used the fortune he made as a brewer to finance his telescopes.

All of the moons of Uranus are named after characters in plays written by William Shakespeare. The largest moon of Uranus is Titania (named after a character in A Midsummer’s Night Dream) , which measures over 900 miles in diameter and orbits Uranus from a distance of about 240,000 miles.

Does Neptune have any rings? Neptune has 5 (FIVE) ring but they're too faint to see *Added* They are broken rings or in some cases ring arcs 3 of them are narrow and 2 of them are wide. Yes, Neptune has several faint rings around it. There are three main rings which are very thin and dark. The rings are made up of small rocks and dust. Neptune's rings are not the same thickness all around. There are areas of the rings which are much thicker than other areas of the rings. These thicker parts are called ring arcs. Some of these ring arcs are also twisted. Because Neptune's rings are so dark and faint, they were not discovered until the 1980s.

How Many Moons Does Neptune Have? With the exception of Triton and Nereid, Neptune’s irregular moons are similar to those of other giant planets and are believed to have been gravitationally captured by Neptune. In terms of size and mass, the irregular moons are relatively consistent, ranging from approximately 40 km in diameter and 4 x 10 16 kg in mass (Psamathe) to 62 km and 16 x 10 16 kg for Halimede.

The Planet Neptune Neptune takes 16 h 6 min 36 s (0.6713 days) to complete a single sidereal rotation, and 164.8 Earth years to complete a single orbit around the Sun. This means that a single day lasts 67% as long on Neptune, whereas a year is the equivalent of approximately 60,190 Earth days (or 89,666 Neptunian days). Because Neptune’s axial tilt (28.32°) is similar to that of Earth (~23°) and Mars (~25°), the planet experiences similar seasonal changes.
