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.
Prior to 2006, the official count of planets was 9 because Pluto was reclassified in this year from being a planet to being a dwarf planet. The number of planets pre 1930 : 8 Before the discovery of Pluto (in 1930), there were only 8 planets - the same official 8 planets that we have today. The number of planets pre 1854 : 8 - 23 From 1801 to the 1845 there were up to 23 planets.
