for remember it only that pluto was included in the category of planets.
Since the discovery of Pluto in 1930, astronomers have incorporated Pluto into the category of planets in our solar system, so until 2006 there were nine planets in our solar system. However, in a conference dated August 24, 2006 in Czechoslovakia, astronomers incorporated in the International Astronomical Union (IAU), decided that pluto was included in the category of planets.
