Nobody knows exactly.
Normally, planetary rings are made up of rocks caused by impacts between planets, moons and asteroids.
However, Neptune is not a solid planet, so there is nothing for other space objects to impact on. Also, Neptune's rings are very faint and incredibly difficult to see.
Therefore astronomers think the rings of Neptune are made of micrometre dust (dust the size of a millionth of a metre) and ice particles.
gas, water, and rocks
platnum
part of neptunes rings are thick and thin. they are also twisted and made of rocks there are 5 of them
Neptune has 13 rings and they are made up of dust particles
No they were discovered in 1968 by Edward Guinan
Voyager 2 flew by Neptune in 1989, taking images of of Neptunes thin ring system that cannot be easily seen from Earth.
The four gas giant each have rings. Jupiter, Saturn, Uranus and Neptune. Saturns rings are most prominent, less so are the rings of Uranus. Neptunes and Jupiter rings are very feint.
Neptunes rings are made up out of gas.
