I wish to add something here, something I learned in my graduate courses in Philosophy some 12 years ago. There is an expression called 'evening star', and another called 'morning star'. They both refer to the same thing, namely the planet, venus. Since this object appears first to the naked eye, and is very bright that can be seen even before dark, it is called by this name. The expressions have different meanings, but the same reference. But the name 'Planet Venus' clarifies that it is not a star, but planet, and the notiion of what astronomical objects are planet are well defined.
Totally off-topic but couldn't resist this - 'Planet' is being redefined :)
