Example Sentences

This paper explores the scenario where large regular exomoons escape after tidal interchange of angular momentum with its parent planet, becoming small planets by themselves. We name this hypothetical type of object a ploonet.

For now, such leftover debris fields may be the best chance for astronomers to infer the existence of ploonets. After all, even if astronomers detect a runaway ploonet orbiting its host star, it would be hard to distinguish it from normal planets.
