in 2006 the IAU(international astronomical union) passed out this resolution that changed the definition of a planet, it says that a planet must be a celestial body that oribtis around the sun, has a round shape, and has a clear neighborhood around itz orbit. Pluto sometimes crosses over to Neptune therefore it is not a planet, however, wat i dont get is, Venus and Mercury is located in Earth's orbit, y are they still considered to be a planet?
