Tchos just sent me a link to a nice Dwemere orrorey and I want to make it lore correct. Does anyone know of any information on the phases of the moons, what the planets are called, where there located etc. I'd like to make it as accurate as possible.

The http://www.imperial-library.info/astro/ and the http://www.imperial-library.info/obscure_text/cosmology.shtml contains pretty much all the information on the topic.
