The official group, The International Astronomical Union, that names objects in the solar system has come up with a category for objects formerly called “dwarf planets” or objects that circle the sun and are too small to be considered planets but are big enough to have their own gravity. These objects will now be referred to as “plutoids” after the planet that was demoted to dwarf status. The astronomical union, which is meeting in Oslo, Norway, raised a cosmic fuss two years ago when it demoted Pluto. There are only two plutoids: Pluto and Eris.
