Talk:Selûne (moon)

Distance discrepancy
The distance between Toril and Selûne given in the Forgotten Realms Campaign Setting 3rd edition is quite bizarre. It says that it is 2000 miles across at a distance of 20,000 miles (for comparison, Earth's moon has roughly the same diameter but lies at a distance of 238,000 mi).

Astronomically, that doesn't make sense. An object of that size that close would have an angular diameter of 5 degrees. That's ten times larger than our moon appears in Earth's sky! (Again, for comparison, Earth's moon has an average angular diameter of around 0.5 degree.)

On the other hand, Realmspace puts Selûne at a much more reasonable distance of 183,000 miles, which, for an object of the same size, would result in an angular diameter of 0.6 degree. Larger than our moon, as is stated in multiple sources, but not by much. Even magic must give way to geometry. :)

Is there any other source that corroborates the weird 20,000 miles? If not, I think it should be considered a typo, and the value from Realmspace should be adopted instead. &mdash; Sirwhiteout (talk) 01:10, January 30, 2018 (UTC)
