Im going to assume that the article you re referring to is ' How pluto stopped being a planet ' by Tyrone Nielson.
The main idea of the article is that a group of astronomers decided not to recognize pluto as part of our solar system by calling it a dwarf planet. But they do not call it that because of its size, but in order to be called a planet it has to follow three conditions, of which it does not fulfill the thrid one, which is that a planet must attract smaller objects to itself or pull them to its orbit or throw them into space but pluto moves with a field of rock and ice that can not be rid of. That s why the name of dwarf planet.
