Where is the dwarf planet Pluto gone?In which galaxy it is now?

Properties of a dwarf Planet:

• It is a celestial body which orbits around the Sun.
• Sufficient mass for self gravity.
• Not cleared the neighbourhood around its orbit
• is not a satellite

Main reason for considering Pluto as dwarf Planet: It failed to clear the objects in its orbit. 

Pluto was reclassified as dwarf planet in the year 2006. But, its position is not changed.
Hence, it has not gone anywhere and still belongs to Milky way Galaxy only.
