Sejak Himpunan Astronomi Internasional menetapkan definisi plutoid, makemake termasuk kelompok ini bersama pluto dan eris karena memenuhi ketentuan sebagai objek besar, bulat, dan berada lebih jauh dari neptunus.
Since the International Astronomy Union determined the definition of Plutoid, the Makemake was included in this group along with Pluto and Eris because it fulfilled the provisions as big, round object and located farther than Neptunus.
