A dated view of a changing orbit
This record uses JPL solution JPL 61, with element epoch JD 2456550.5 TDB. Its osculating eccentricity is 0.409059, inclination 9.17169°, and perihelion distance 2.05016 AU. These describe an instantaneous fitted conic; planetary encounters can change the future orbit.
The explorer evaluates a two-body overview at the selected date. A bounded Horizons vector request offers a separate source-calculated path. The two models can disagree, especially during encounters and far from the element epoch.
