Example Sentences

"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."
"Now we get exoplanets, dwarf planets, rogue planets, and (exo)moons. That's ok, but then comes the utter silliness: none of them are planets. Even those bigger than Jupiter aren't planets."
