If Triton, Neptune's moon is a captured satelite with a retrograde orbit, how long will it take to be broken?

Question

down into rings?

Answer 1

It hasn't happened yet, and it's been orbiting for a while.

Check back in a week or two and see if anything's changed.

Answer 2

just as long as any other moon orbiting a planet.

in fact, with no other moons to risk crashing into, and being large enough to withstand such, probably longer than most.

however, being very cold, will make it more brittle and somewhat increase the chances.

Answer 3

Several million years they theorize.

Answer 4

It's such a large body, I doubt it'll be broken down, unless one or more very large objects hit it.
