Hey, guys-- it's always bothered me when thinking about it, but let's say that, hypothetically, a large moon such as Europa, Io, Ganymede, Callisto, or Titan suddenly escaped their planet's orbit--(I know there's very little chance of that ever happening, but just pretend)-- and then fell into a stable orbit of it's own, clear of debris/etc. Would the escaped moon be reclassified as a planet, a dwarf planet, or something new, like a 'rogue lunar body?'

What's the least remarkable moon?
