Does pluto have enough mass/gravity to clear out the objects? or it does not have enough mass/gravity to do it?

Pluto is not a planet anymore and if it was then the Answer is no

No it does not. To be considered a planet, one of the factors that it needs to achieve is the ability to "clear the neighborhood" where it clears the objects around it. It has a weak gravitational pull so it can't completely clear objects, only small ones.

The answer is exciting networking.
