Pluto was ruled not a planet anymore because it is a "dwarf  planet"

Apparently, the International Astronomical Union's (IAU) definition of a planet includes that a planet should be part of a body that would orbit the sun.  

According to the IAU, there are three criteria's that contribute to a planet being called a planet.

1. It is within orbit around the Sun.

2. It has a sufficient mass to assume a nearly round shape

and 3. It has "cleared the neighborhood" around it's orbit.

Pluto only so happens to meet 2 of these requirements, not including the third option.
