Why isn't PLUTO considered a PLANET any more?

Did you know that Pluto is no longer considered a planet?

Nine years ago, a group of astronomers decided that Pluto would not be called a planet anymore, but a dwarf planet instead.The 3 criteria (or reasons) for a planet are:

• It orbits around the Sun.

• It has a nearly round shape.

• It has "cleared the neighborhood" around its orbit.

Although Pluto revolves around the Sun and has a nearly round shape,  it has not “cleared its orbital region”. This means that Pluto cannot get other bodies out of its orbit (or path).Large bodies, including Pluto, that do not meet all three criteria are now called  “Dwarf planets”.
