中文释义

英文释义

名词 n.
  1. A moon that is outside the Solar System (our solar system).
    — Of course we can't detect exomoons now (or for a long while), but could planets like 51 Peg b have any moons? Wouldn't the star strip them off? I don't suppose there can be a moon around a planet that orbits in more time than it takes that planet to orbit its star.
