Orbital character
A measured small-body path in the shared reference frame
Hygiea follows a catalogued path with a 3.141 AU semi-major axis, eccentricity 0.112, and 3.83° inclination. The resulting two-body period estimate is 5.567 Earth years; the representation notes below state the source epoch and precision boundary used by Explore.
Catalogue context
Hygiea among its nearest Helios peers
Hygiea is linked with Ceres, Vesta, Pallas inside the Helios main-belt 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.
