The Earth's Moon is about 1.5 times bigger than Pluto.
The earth's moon is an extreme outlier to our knowledge. Thea made our world weird
Is it an outlier because the moon is a pretty big satellite for such a snall planet?
And Titan is 6% bigger than Mercury.
in Asimov's Foundation series, there is (was) a galaxy-spanning human civilization, but Earth was lost and mostly considered mythical. One of the arguments against it actually existing was the absurdity of such a double planet system existing. In the wider galaxy only giant planets had such large satellites.
In his books were they similarly absurdly tiny, rotating in irregular orbits well outside of their class of planets, and inhabiting an entire solar system of similarly sized unremarkable objects?
And the 2006 decimation of planet that made Pluto not a planet explicitly added "must not orbit another object" to stop the moon from being a planet.
