Why is Pluto no longer a planet? In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of dwarf planet.. This means that from now on only the rocky worlds of the inner Solar System and the gas giants of the outer system will be designated as planets.
Best Answer: It was IAU (international astronomical union) who set rules to define what a planet is in 2006. Pluto failed to fit in the category of planets. This doesn't mean that pluto is anything different than what it was in 2005. It just means the definition of what a planet is has changed.
