Pluto was excluded from the list of planets in 2006 after the International Astronomical Union (IAU) released it's decision on what defines a planet. In sum, the IAU now defines a planet as being a celestial body within a solar system that:
1. orbits the sun
2. is large enough to form into a round-ish shape
3. has "cleared the neighbourhood" of it's orbit
Since Pluto did not meet the third criteria, it can no longer be considered a planet.
What else can I help you with?
When did scientists describe Pluto as a dwarf planet?
In 2006 the Astronomical Union defined 'planet' and the definition excluded Pluto. At the same time they created the term dwarf planet into which Pluto fell.

What planet of the solar system is exception?
Pluto is often considered an exceptional planet as it was reclassified as a dwarf planet by the International Astronomical Union in 2006 due to its small size and different orbit compared to the eight classical planets.
What planet was removed from the planet status in recent years?
Pluto was removed from the list of planets in 2006 by the International Astronomical Union, as it did not meet the criteria to be classified as a planet due to its size and orbital characteristics.

Which planet has been excluded and why?
Pluto has been excluded because to be a planet, you have to be able to: orbit the sun, have enough mass to assume a rounded shape, and clear any objects in it's path. Pluto however, does not fit the criteria above, so is now called a Dwarf Planet. hope this has helped! :)
When was Pluto ruled out as planet from the list of planet in the solar system?
In 2006 Pluto was degraded to the status of dwarf planet(there is another dwarf planet, Eris, that is more massive than Pluto).
