It's now considered to be a dwarf planet. Not as prominent as the regular planets in our solar system.

Now pluto is officially a dwarf planet.
It got the boot because it didn't meet the new rules, which say a planet not only must orbit the sun and be large enough to assume a nearly round shape, but must "clear the neighborhood around its orbit." That disqualifies Pluto, whose oblong orbit overlaps Neptune's
Since August 23, 2006 there are just 8 planets in our solar system.

the international astronomical union defined three terms "planet", "dwarf planet", and "small solar system body". this does not change anything about the solar system or pluto. it just corrects the mistake of classifying pluto as a planet initially.
i have known since i was about twelve that pluto does not have the physical and orbital characteristics that fit the pattern set by the major bodies in the solar system, and later, after the discovery of hundreds of other similar bodies with similar orbits, i knew this was inevitable. this was the right thing to do, believe me.
because pluto orbits the sun, is round, orbits the sun with a bunch of other similar bodies with similar orbits, and is not a satellite it is a dwarf planet.
(1) A planet is 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 neighborhood around its orbit.
(2) A dwarf planet is 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, (c) has not cleared the neighborhood around its orbit, and (d) is not a satellite.
(3) All other objects orbiting the Sun shall be referred to collectively as "Small Solar System Bodies".

It has been downgraded to a "dwarf planet" meaning that it :
is in orbit around the Sun
Has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape
Has not "cleared the neighbourhood" around its orbit
Is not a satellite of a planet, or other nonstellar body

It's its own thing called a Pluton.
Pluto, its 3 new friends, and any other large bodies we find in the Ort Cloud will now be classified not as planets but Plutons.

Actually, Pluto isn't classified as a dwarf planet! It is called a pluton planet! I'm not sure if there is such thing as a "dwarf" planet!

A dwarf Planet? That's what I hear, but I don't know the difference!

It is in fact, the biggest ice cube in the solar system.
