Astronomers meeting in the Czech capital have voted to strip Pluto of its status as a planet.
About 2,500 experts were in Prague for the International Astronomical Union's (IAU) general assembly.
Astronomers rejected a proposal that would have retained Pluto as a planet and brought three other objects into the cosmic club.
Pluto has been considered a planet since its discovery in 1930 by the American Clyde Tombaugh.
The vote effectively means the ninth planet will now be airbrushed out of school and university textbooks.
The worst thing is that all the existing ways to remember the order of planets are completely useless.
E.g "Easy ways to remember the order of the planets are the mnemonics: "My Very Excellent Mother Just Sent Us Nine Pizzas" and "My Very Easy Method Just Simplifies Us Naming Planets".
Lose the planets and the pizzas and nothing makes sense any more.
