A dated view of a changing orbit
This record uses JPL solution JPL K264/16, with element epoch JD 2457197.5 TDB. Its osculating eccentricity is 0.587865, inclination 24.2049°, and perihelion distance 1.45509 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.
