Jude 13 calls the ungodly "wandering" what, for whom blackest darkness is reserved?

Answer: Stars

Jude calls them waterless clouds, fruitless trees, wild waves, and wandering stars, for whom blackest darkness has been reserved forever.

“They are wild waves of the sea, foaming up their own shame; wandering stars, for whom blackest darkness has been reserved forever.”— Jude 1:13 (BSB)
