Orbital character
A strongly elongated path around the Sun
Gonggong follows a catalogued path with a 67.5 AU semi-major axis, eccentricity 0.5, and 30.7° inclination. The resulting two-body period estimate is 554.569 Earth years; the representation notes below state the source epoch and precision boundary used by Explore.
Catalogue context
Gonggong among its nearest Helios peers
Gonggong is linked with Pluto, Eris, Haumea, Makemake, Quaoar, 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.
