No. It is now a "dwarf planet."
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.
Pluto fails criterion c because it has many neighbors of similar mass.

NO. We want Pluto to remain a planet, but it isn't. *If you can remember back a few years ago when there supposedly were 40 additional planets, you will know that they were false assumptions* Just like those "40 additional planets," Pluto is a reflection of the light that is reflected off by the other planets.

when i was born, it was a planet. When i was in school it was a planet. I joined the army, it was still a planet. Now that i'm getting old they say it's not a planet. So I think about it. Is Pluto a planet? I don't give a sh*t....

pluto is still a planet but according to NASA those planet who is causing problem as in intersecting with the orbit of the other planets such as neptune n uranus o it is conclude as not part of a solar system

No. I havent though about it till it was declared, but pluto is too strange to still be a planet. It's orbit is crooked and uneven and it is much too small... so small that it is largely affected by its moon's (if you want to call Charon that) gravitational pull. For this reason, it is thought to be a large comet.

To me, and to pop culture, it will never stop being a planet, once something is named a planet, you can't take it away from the popular psyche, those scientists can talk about reasons and sh*t until their brains ooze out their noses, I REFUSE TO LISTEN! LONG LIVE PLANET PLUTO!.

Although a "dwarf planet", it is no longer a planet. And only 260 members of the IAU decided this

It no longer a planet. It is now a dwarf planet. Pluto's new name is 134340.
