What will happen to Triton in the distant future, based on its present orbit?
What will be an ideal response?
Due to its retrograde orbit, it will spiral into Neptune and be torn apart into a ring when it reaches Neptune's Roche Limit. Its tidal forces will probably also heat up Neptune still more; it is already warmer than Uranus.
