Jupiter Heliocentric Trajectory Data in Multiple Coordinate Systems

HelioWeb provides daily heliocentric trajectory data for the planet Jupiter, calculated in Heliographic, Heliographic Inertial, and Solar Ecliptic coordinates. The data originates from NASA's JPL Horizons system and uses the 'Mean of Date' method for the Equinox Epoch. This dataset was last updated by the National Aeronautics and Space Administration on March 13, -2026.

Use Cases

• Modeling solar system dynamics based on heliocentric planetary trajectories.
• Approximating spacecraft ephemeris near planets based on the described small longitude differences.
• Comparing coordinate transformations based on the provided Heliographic, HGI, and SE coordinate systems.
• Studying the drift of the First Point of Aries based on the described Equinox Epoch calculation methods.

Strengths

• Data sourced from the authoritative JPL Horizons system.
• Coordinates calculated using the specific 'Mean of Date' method for the Equinox Epoch.
• Designed for high-precision applications where differences in heliocentric longitude are on the order of 0.25°.

Limitations

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