What happened to Pluto? Did it blow up, or go hurtling out of its orbit? Pluto is still very much a part of our Solar System, it's just no longer considered a planet. In 2006, the International Astronomical Union created a new category for classifying bodies in space: the dwarf planet.

Why was Pluto blown up?

Things went downhill for Pluto in 2006, when the IAU redefined what it means to be a planet, declaring that a planet must be a celestial body that orbits the sun, is round or nearly round, and “clears the neighborhood” around its orbit. Pluto failed on the third account because its orbit overlaps with Neptune.

Was Pluto destroyed?

FYI: Pluto is not destroyed, it is no longer considered a planet as per the definitions of astronomy, and now it comes under the category of "Dwarf Planet".
