    He’s mixed up the first two diagrams - Pluto should be coloured in for the first and not for the second.

      Ultratraditionalist is messed up too. The sun and moon were considered planets when geocentrism was king.

      It comes from the fact that the word planet comes from the Greek and means wanderer. Any celestial body that wandered around compared to the stars was considered a planet.
