Illustration of the Makemake orbit in heliocentric coordinates. Transformation to heliocentric coordinates has removed the ellipsoidal component of the orbit and the epochal sets of observations (chronologically from upper right to lower left) are linearized to good approximation. All WISE observations during which Makemake was in the field of view are marked with a dot. The WISE detections of Makemake are marked with a red cross.
