I recall that the green Lune is said to be 50,000 leagues away, which we 
have generally taken to mean 150,000 miles and indicate that it has 
moved closer somehow. Maybe instead, the units conversion error is in 
the past of urth, in all or in part, so that learned people of 
Severian's time are parroting an error made popular by some respected 
historian and "G.W." is caught up in it as well.

This could mean that the Wall's dimensions are overestimated by a factor 
of 5:3, which is still pretty big, or it could mean that a measurement 
that G.W. has chosen to translate as "league" has different meanings or 
different idioms for measurements in space than for measurements on the 
ground, or for vertical height vs length.

(It also occurs to me that if the moon's orbit hasn't changed, it's 
gravity and natural lack of atmosphere probably haven't either. In fact, 
the low gravity and lack of weather make it an ideal candidate for being 
largely domed over, similar to the Botanical Gardens.)
