You know... Pluto was considered a planet until quite recently. In fact, most school texts pre-2006 will list Pluto as the ninth planet in our Solar System. In 2006, they finally defined what a planet should be or listed a set of criteria for a celestial body to be called a planet and Pluto fell short.. and got redefined as a dwarf-planet.

Fun fact.. if you did consider it a planet.. its orbit is so wonky that it used be the eight planet from the sun during some parts of its orbital cycle - meaning it was closer than Neptune at times.
