(In actuality, stars do move, but ancient astronomers lacked the precision instruments to measure this.) However, the ancients classified a second group of stars as wandering stars because, unlike the fixed stars, they appeared to "wander" across the sky.
The wandering stars are, in fact, planets that are visible to the naked eye, and the brightest of these -- the third-brightest object in the sky -- is Venus.
Venus does indeed have a dual nature: it is known as both the morning star and the evening star. The ancients thought of these two stars as two separate objects, even going so far as to give them different names.
And the Roman goddess Venus is, of course, associated with love, among other things, so that certainly explains some thematic elements of the show as well as the hearts on Star's cheeks. (I also think there's a little bit of Sailor Venus going on with Star.)
