  • $\begingroup$ "7 times brighter" is ill-defined. 7 times the area? 7 times the radius? There's a big difference! $\endgroup$

  • $\begingroup$ Also, now I come to look at it, it might be kinda small in either case. Saturn as seen from Titan has about 10 times the angular diameter, and so about 100 times the area. Jupiter as seen from Callisto is ~9 times the angular diameter of the moon. $\endgroup$

  • $\begingroup$ ...aaaand thinking about it even more, it isn't possible to have a stable orbit around a saturn-sized gas giant orbiting a sun-like star that gives you a viewpoint where saturn is 7 times the apparent area of the moon. $\endgroup$
