And another question, why are neptune's rings so difficult to observe?

The planet's rings are difficult to see because they are dark and vary in density and size. Astronomers think Neptune's rings are young compared to the age of the planet, and that they were probably formed when one of Neptune's moons was destroyed. What are some reasons why Neptune receives such a small amount of sunlight? The atmosphere Like the other giant planets, Neptune's outer atmosphere is composed predominantly of hydrogen and helium.

Then, why do we think that ring particles must be replenished over time where we think ring particles come from choose the correct statement? Why do we think that ring particles must be replenished over time? Because collisions are constantly occurring within the ring systems, ring particles are continually being ground down to dust. Dust cannot survive long in ring systems because sunlight pressure makes the particles slowly fall onto the planet.

Uranus's rings are trapped among the orbits of small moons and Uranus's moons show evidence of having been impacted. Subsequently, what is neptune's rings made out of? 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.
