Is there any PIE word for Venus/Morning/Evening Star? In many languages Morning Star is linked to Dawn: Greek Eosphoros, Latvian Usins^. Sanksrit Us^anas is not related to *aus- root, but his epithet S^ukra means "bright" (*k^ukro-). I have no idea for explaining Latin Jubar, but a reflex of *aus- may be present in OE earendel/ON aurvandill.
I'd like to see your comments; what's know about IE names for stars and planets?
