Orbital character
A measured small-body path in the shared reference frame
Quaoar follows a catalogued path with a 43.69 AU semi-major axis, eccentricity 0.039, and 7.99° inclination. The resulting two-body period estimate is 288.784 Earth years; the representation notes below state the source epoch and precision boundary used by Explore.
Catalogue context
Quaoar among its nearest Helios peers
Quaoar is linked with Pluto, Eris, Haumea, Makemake, Gonggong, Sedna, Orcus inside the Helios outer-system selection. The grouping keeps adjacent reading coherent; it does not imply that these bodies share the same composition, origin, or present physical state.
