Question

How often do Saturn's rings disappear? What causes this to happen?

Answer 1

Saturn's rings change its angle with respect to earth observers in 14 years..It is called ring plane crossing.

Explanation:

So,once in 1 4 years they become very thin and observer will feel,it disappeared..Galileo observed the missing rings of Saturn.The same thing that's happening now: we're experiencing a "ring plane crossing." As Saturn goes around the sun, it periodically turns its rings edge-on to Earth—once every 14-to-15 years. Because the rings are so thin, they can actually disappear when viewed through a small telescope. Beta/NASA Picture canadinword press.com.
