One thing that's always interested me is how, as I child I always read/was told, that the Gods in Roman/Greek mythology, where the stories' characters match constellations, that these Gods were made into stars in the sky, and that's why the constellations are named after them.
Given that many ancient cultures put so much faith in the Heavens and the movements of the stars and planets, that it would make more sense to look at it the other way round, and say that the Gods were named after the constellations, not the other way around, and thus their respective mythologies are allegories for the movements and relationships that stellar objects have, in relation to each other viewed here from Earth.
The ones that seem to be named "before the fact" are those that are associated with non-gods. "There's a group of stars that look like a wagon, so, see, that's actually Thor's wagon." But making a god out of a pattern in the sky... no. There's no evidence this ever happened.
Very few constellations were named after gods. Planets usually were, but not constellations.
