In a real sense the connection would be left up to each individual person, because only you know what symbolism you intended to evoke from your character. There are a fuck load of constellations all across different cultures, so finding one to associate with a particular trait of a character shouldn't be too difficult. In a world building/story sense, it could be an old Rukongai tradition to refer to special people that was revived when Central 46 needed a means of tracking those it considered dangerous. Someone starts referring to one of the Jūsanseiza by a related moniker and it just caught on from there.
