FWIW, before Disney partially reset the canon, Endor (the moon) was actually established (despite the common references to “the forest moon”) to also have grasslands, deserts, etc., as seen in the two made-for-TV Ewok movies.
I always liked the fact that Palpatine referred to the Forest Moon as the Sanctuary Moon. Like it was his own name for the place, but absolutely nobody else used it, so he just went on using the name to piss people off and be all passive-aggressive about it.
He had Vulcan being blown up, and clearly visible from a neighboring planet... and in tFA, the entire Republic (all five planets) was destroyed by a single shot from a canon apparently also in the same solar system as the entire republic.
He’s just not good at judging distances it appears.
