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.
Caltech's Brown added that, even if Pluto is proven to be the biggest dwarf planet, it's not likely to be reinstated on that evidence alone. (Related: Pluto a Planet AgainâOn Friday the 13th, in Illinois.) After all, size isn't the only thing that matters in the new definition of a planet.
