In 2005, Eris, a dwarf planet in the scattered disc which is 27% more massive than Pluto, was discovered. Therefore the scientist have to change the defination of the term'PLANET'. This the reason why Pluto is considered as a Dwarf planet. I don't think so there are aliens on that planet.

here is your answer
>>>One of the criteria for being classed as a planet is that an object must have “cleared the neighbourhood around its orbit." The Earth’s mass is 1.7 million times the mass of the other objects in its orbit. Unfortunately, Pluto’s mass is only 0.07 times the mass of other orbiting objects. Because of this, on September 13th 2006 Pluto was officially downgraded to a ‘dwarf planet.’
>>>The only difference between a planet and a dwarf planet is the area surrounding each celestial body. A dwarf planet has not cleared the area around its orbit, while a planet has.
