Was “pluto is a planet” ever true?

Abstract
In 2006, much to the dismay of many amateur (and some professional) astronomers, the International Astronomical Union (IAU) voted to adopt a definition of „planet‟ which excluded Pluto from the extension of the term. Since its discovery in 1930, Pluto has been designated one of the nine planets in our solar system – veritable celestial royalty among the thousands of objects that make up this system. But with the discovery of a number of objects of similar size and orbit to Pluto,i it was recognized that these objects – and potentially hundreds of others – would have be reclassified as planets or Pluto would have to lose this status. And the IAU chose the latter course of action.
