* In ''TabletopGame/TheWorldOfDarkness'' supplement ''Infinite Macabre'', the term "galaxy" is explicitly stated to mean "systems of stars orbiting one another" or "systems of planets orbiting one or more stars." Also, they're separated by hundreds of thousands of parsecs at least, millions of parsecs at most. By way of reference, the nearest "galaxy," using the above definition, to our "galaxy, again using the above definition, is the Centauri system, roughly 1.5 parsecs away. Talk about scale problems...

* In ''Literature/FoundationsEdge'', Trevize and Pelorat are discussing a legend about a particular pentagon of stars. Pelorat assumes it's a legend centuries old, but Trevize states it must be a recent one and, moreover, one originating from the particular system they are in, because there is only one inhabited system from which the stars form a perfect pentagon. Moreover, it is comprised of stars with high proper motion, and was noticeably distorted as late as a century ago.

** That would be the case in summer, but not winter (or spring and fall for that matter). So this doesn't hold unless they specifically said they'd met there in the summer.

* Since UsefulNotes/Uranus is not visible from earth using the [[HehHehYouSaidX naked]] eye, anyone who invokes UranusIsShowing is pretty obviously talking about someone's bunghole rather than the planet.

* In the ''ForgottenRealms'' Player's Handbook for ''TabletopGame/DungeonsAndDragons 3.5'' is stated that Selûne, the Abeir-Toril's moon, orbits at just 20,000 miles of the planet (for comparison purposes, this is less than 1/12th of the mean distance between the Moon and the Earth)[[note]]Retconning likely by error the previous version, where it was stated to be [[http://www.spelljammer.org/worlds/Realmspace/Toril.html 183,000 miles]] away[[/note]]. The effects of having a large satellite (it's stated to be similar in size to the Moon) so close such as ''very'' powerful tides and tidal-caused earthquakes are not addressed at all[[note]]Nor the spectacularity of a full moon night with one so large. Nor the possibility of the moon crossing the Roche limit and being ground into gravel.[[/note]].

* This is OlderThanPrint. In ''Literature/TheDivineComedy'', Dante violates a principle of medieval astronomy, that the Sun, Mercury, and Venus were always close as they orbited Earth, in order to have Mercury and Venus appear in the shadow of the Earth. Doing so allows Dante to use [[DarkIsEvil darkness to symbolize the deficiencies of the souls of Mercury and Venus]].

** Or maybe Yavin is a young world that is still glowing hot from the residual heat of its formation. [[https://arxiv.org/abs/1101.0606 Saturn and especially Jupiter]] are stated to have been hot enough just after that event to shine like tiny suns.

* While it may have simply been caused by a "0" that got lost while writing the book[[note]]In the previous edition, it was ten times (or more) further away[[/note]], in the ''ForgottenRealms'' Player's Handbook for ''TabletopGame/DungeonsAndDragons 3.5'' is stated that Selûne, the Abeir-Toril's moon, orbits at just 20,000 miles of the planet (for comparison purposes, this is less than 1/15th of the mean distance between the Moon and the Earth).
