Orbital character
A visibly non-circular solar orbit
Pluto follows a catalogued path with a 39.482 AU semi-major axis, eccentricity 0.249, and 17.16° inclination. The resulting two-body period estimate is 248.084 Earth years; the representation notes below state the source epoch and precision boundary used by Explore.
Catalogue context
Pluto among its nearest Helios peers
Pluto is linked with Eris, Haumea, Makemake, Quaoar, 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.

What Explore is showing
A bundled frozen six-element preview preserves the documented body scope. It was not freshly re-fetched from SBDB in this build environment and must not be presented as an accurate or current ephemeris.
