Comet Borrelly Daily Heliocentric Trajectory Coordinates in HG, HGI, and SE Systems

Heliocentric trajectory data for Comet Borrelly, calculated using the 'Mean of Date' method for the Equinox Epoch. The data is provided in Heliographic (HG), Heliographic Inertial (HGI), and Solar Ecliptic (SE) coordinate systems, sourced from NASA's JPL Horizons system. The dataset is maintained by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling comet trajectories based on daily heliocentric coordinates.
• Analyzing solar system dynamics based on coordinate transformations between HG, HGI, and SE systems.
• Providing reference ephemeris for spacecraft navigation based on the description of using planet orbits as a proxy.
• Studying the drift of the First Point of Aries (FPA) based on the discussion of Equinox Epoch calculation methods.

Strengths

• Data originates from the authoritative JPL Horizons system, a standard source for solar system ephemerides.
• Coordinates are calculated using a defined 'Mean of Date' method for the Equinox Epoch, providing methodological clarity.
• Provides data in three standard astronomical coordinate systems (HG, HGI, SE) for comparative analysis.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality and precision require manual inspection after download.
