Do not say "the 9 planets of the Solar systen", from now on, make that 10.

It was reported that the 10th planet of the solar system was found, farther from the Sun then Pluto, the 9th. It is now called "2003UB313", with a size bigger then Pluto, and a similar icy, rocky surface. It was discovered using the Samuel Oschin Telescope at Palomar Observatory near San Diego, CA. The discovery was announced on July 29 by planetary scientist Dr. Mike Brown of Cal-Tech in Pasadena, Calif., whose research is partly funded by NASA.

However, some may say that this is the "real" 9th planet since Pluto is considered by some as an "astroid" instead of a planet.
