For 10 points—in approximately 100 million years, what satellite will either create a ring around, or crash into, Neptune?
Discovered in 1846 just a few weeks after the planet it orbits, it moves in a retrograde orbit, which may means that it was captured by its planet after forming. Additionally, tidal interactions with its planet result in its orbit losing energy, so it is spiraling inwards.
