Is there anything special about Neptune's moons?

Answer 1

Neptune has 13 known moons. The largest by far, comprising more than 99.5 percent of the mass in orbit around Neptune and the only one massive enough to be spheroidal, is Triton, discovered by William Lassell just 17 days after the discovery of Neptune itself. Unlike all other large planetary moons in the Solar System, Triton has a retrograde orbit, indicating that it was captured rather than forming in place; it probably was once a dwarf planet in the Kuiper belt. It is close enough to Neptune to be locked into a synchronous rotation, and it is slowly spiraling inward because of tidal acceleration and eventually will be torn apart, in about 3.6 billion years, when it reaches the Roche limit. In 1989, Triton was the coldest object that had yet been measured in the solar system, with estimated temperatures of −235 °C (38 K).

Neptune's second known satellite (by order of discovery), the irregular moon Nereid, has one of the most eccentric orbits of any satellite in the solar system. The eccentricity of 0.7512 gives it an apoapsis that is seven times its periapsis distance from Neptune.

From July to September 1989, Voyager 2 discovered six new Neptunian moons. Of these, the irregularly shaped Proteus is notable for being as large as a body of its density can be without being pulled into a spherical shape by its own gravity. Although the second-most-massive Neptunian moon, it is only one-quarter of one percent the mass of Triton. Neptune's innermost four moons-Naiad, thalassa, Despina and Galatea-orbit close enough to be within Neptune's rings. The next-farthest out, Larissa was originally discovered in 1981 when it had occulted a star. This occultation had been attributed to ring arcs, but when Voyager 2 observed Neptune in 1989, it was found to have been caused by the moon. Five new irregular moons discovered between 2002 and 2003 were announced in 2004. As Neptune was the Roman god of the sea, the planet's moons have been named after lesser sea gods.

Answer 2

• Neptune is the fourth largest planet in our solar system
• Neptune has thin rings
• Neptune is tilted on its side.
• Neptune is really cold.
• Neptune is named after a sea God
• It's the strong winds that make Neptune special
• Neptune is made of gas.
• Neptune does not have land.
• Neptune is -153 degrees Celsius.
• Neptune's orbit is 59,000000000km
• If you are 11 year old then you well be 4 years old on Neptune
• Neptune is the eighth, or last, planet in our solar system.
• Neptune is located between Uranus and Pluto.
• Neptune is a very long way away from the Sun. Its average distance from the Sun is almost 4.5 billion kilometers., or over thirty times the distance from Earth to the Sun.
• The orbit, or path, Neptune follows around the Sun is almost a perfect circle. The closest Neptune gets to the Sun is about 4.3 billion kilometers., and the furthest away it gets is a little over 4.6 billion kilometers. At this distance, the Sun is just another bright light in Neptune's sky.
• Neptune is green but looks blue
• Neptune has rings
• Neptune is the smallest gas planet

Answer 3

Neptune's largest moon is Triton, which is actually one of the largest moons in the SolarSystem. Triton was first discovered by William Lassell just 17 days after Neptune itself was discovered.

It took another 100 years for Neptune's second moon, Nereid, to be discovered. Nereid was discovered by Gerard P. Kuiper, who the Kuiper Belt is named after.

And that's all the moons that astronomers thought Neptune had until 1981 when its third moon, Larissa, was discovered.

Astronomers lost track of Larissa until NASA's Voyager 2 spacecraft flew past Neptune in 1989. Voyager 2 found Larissa again, and discovered 5 additional inner moons: Naiad, Thalassa, Despina, Galatea and Proteus. After Voyager 2′s flyby was complete, the total forNeptune's moons rose to 8.

And then in 2002 and 2003, astronomers uncovered 5 additional moons circling Neptune using Earth observatories. The newly discovered moons were named Halimede, Sao, Psamathe, Laomedeia, and Neso.

And that's how we reached the current total of 13 moons for Neptune.

Of course, if you ask the question again in a few years, it might be higher, since astronomers are working to uncover new moons around the planets all the time.

Answer 4

Yes, Neptune has 14 known moons, with Triton being the largest and most famous. Triton is unique among large moons in our solar system because it orbits in the opposite direction of Neptune's rotation, suggesting it may have been captured from the Kuiper Belt. Additionally, several of Neptune's other moons exhibit irregular orbits and compositions, making them distinctive objects of study.
