The IAU members gathered at the 2006 General Assembly agreed that a "planet" is defined as a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.
This means that the Solar System consists of eight "planets" Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. A new distinct class of objects called "dwarf planets" was also decided. It was agreed that "planets" and "dwarf planets" are two distinct classes of objects. The first members of the "dwarf planet" category are Ceres, Pluto and 2003 UB313 (temporary name). More "dwarf planets" are expected to be announced by the IAU in the coming months and years.

It has been demoted to a minor planet. The reason for this are two-fold: 1) Charon, Pluto's moon, actually qualifies as a minor planet on its own, and if Pluto was to be recognized as a major planet, so must Charon, and 2) Pluto doesn't "own" its orbit--its orbit cross into Neptune space for half of the time, and that kind of ambiguity was decided to be very "unplanetlike".
However, only 300 of the 2,400 astronomers of the International Astronomical Union actually voted for the change, so don't be surprised if it get changed back within the year or so.
Hope that helps.

No, it is there in the solar system. It's just been demoted fro its status as a planet to dwarf planet(bcoz its small). Scientists are crazy sometimes.

They're not saying it isn't part of the Solar System--that would be presumptuous, I agree--just that it's not one of the eight planets. It sounds really weird saying that last bit.

Yea, they say it's no longer a planet, but it's still in the solar system, just not as a planet.

No, it's just been demoted. People always pick on the smallest.
