Factual error: In numerous sci-fi films and TV series, planets, moons, and other similar celestial objects always appear to have gravity equal to that of Earth regardless of the object's size or mass. For example, a moon the same size as a small planet (such as Yavin 4 or Endor's forest moon from the Star Wars films) has the same apparent gravity as larger bodies, while in reality, the smaller objects would have noticeably less gravity than larger ones.
