    Most commonly it is being said that the oblong orbit of Pluto overlaps with Neptune's and that's why Pluto is not considered as a planet. Now Pluto is known as "dwarf planets".

    THERE ARE THREE CONDITIONS ON WHICH A BODY IS CONSIDERED AS A PLANET. THEY ARE: FIRST A IT SHOULD ORBIT THE SUN DIRECTLY AND NOT ANY OTHER SOLAR SYSTEM BODY SECOND IT MUST HAVE SUFFICIENT MASS TO PULL ITSELF INTO AN ALMOST ROUND SHAPE THIRD IT SHOULD CLEAR ITS NEIGHBORHOOD AROUND ITS ORBIT THE THIRD POINT IS NOT FULFILLED BY PLUTO.ITS LOCKED BETWEEN THE RESONANCE ORBIT WITH THE MUCH-LARGER NEPTUNE.HENCE IT IS NOT CONSIDERED AS A PLANET. IT IS NOW CALLED A DWARF PLANET.
