Solar Orbiter Trajectory Data in Heliographic and Solar Ecliptic Coordinates

Solar Orbiter Ephemeris provides heliocentric trajectory data for spacecraft and celestial bodies like Comet Borrelly. The data is calculated from JPL Horizons orbit data using the 'Mean of Date' method for the Equinox Epoch. NASA produced this dataset, which was last updated on March 13, 2026.

Use Cases

• Model spacecraft heliocentric trajectories based on ephemeris data.
• Compare coordinate systems for celestial objects based on Heliographic (HG), Heliographic Inertial (HGI), and Solar Ecliptic (SE) frames.
• Calculate proxy ephemeris for spacecraft near planets based on planetary orbit data.
• Analyze the drift of the First Point of Aries (FPA) based on different Equinox Epoch calculation methods.

Strengths

• Data originates from the authoritative JPL Horizons system.
• Coordinates are calculated using the 'Mean of Date' method for the Equinox Epoch.
• Last updated on March 13, 2026.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
