It is deliberately contrasted with Basri's suggested Definition Of Planet ("''a planemo that orbits a Fusor ''") and was designed as a potential solution to the debate over what constitutes a planet. It can be considered helpful as it creates a designation for so-called " Interstellar Planet s" that are otherwise not covered by suggested definitions for 'planet', and it also creates a category to group large, compositionally-similar moons with their planetary counterparts. The term is a contraction of ''plane''tary '''''m'''''ass '''''o'''''bject. If applied to our own solar system the list of planemos would probably read: # Mercury # Venus # Earth # Ceres # Jupiter # 2003 EL61 # Quaoar # 2005 FY9 # 2003 UB313 # Sedna The numbered planemos would count as Planet s if Basri's definition for the term was used. Although potentially several more could exist and not yet be discovered. However, as the definition of "roundness" might be arbitrary, an eventual list could vary from this. For example, 2003 EL61 is less spherical and more of an oblong shape. Basri notes 'roundness' requires "enough Mass to allow their self-gravity to overcome any material forces that might produce Asymmetric shapes" and that "technically roundness means conformity to the Equipotential Surface ".
