Expert Answer
Yes, Pluto is reclassified as dwarf planet. After 1992, the status of Pluto as a planet was questioned as it was found that other celestial bodies also share its orbit. In 2006, International Astronomical Union (IAU) define the term planet which states that the planet is - a) in orbit around the Sun b) It has sufficient mass to assume hydrostatic equilibrium (i.e. a nearly round shape) and c) It has "cleared the neighbourhood" around the orbit ( which means its orbit must not be shared by any other celestial objects).
As Pluto does not satisfy this condition it was reclassified as a dwarf planet.
