New research from the University of Central Florida in Orlando claims the reason Pluto lost its planet status is 'not valid'. THE GEOPHYSICAL DEFINITION Scientists have proposed a new way to define planets based on 'the physics of the world itself.' Since Neptune's gravity influences its neighboring planet Pluto, and Pluto shares its orbit with frozen gases and objects in the Kuiper belt, that meant Pluto was out of planet status. Instead, Metzger recommends classifying a planet based on if it is large enough that its gravity allows it to become spherical in shape. 'In peer-reviewed planetary science publications and talks, the world 'planet' often substitutes for the given name of the world, even if the world is a moon or a dwarf planet.'
