Module orbital_3d Copy item path Source RingCrossingAnalysis Result of analyzing whether a transfer trajectory crosses Saturn’s ring plane. UranusApproachAnalysis Result of analyzing Uranus approach geometry. ENCELADUS_ORBITAL_RADIUS_KM Enceladus orbital radius: ~238,020 km (outside ring system)
Note: NASA JPL gives semi-major axis 238,042 km; 238,020 km is used
throughout EP02 calculations for internal consistency. SATURN_EQUATORIAL_RADIUS_KM Saturn equatorial radius: 60,268 km SATURN_OBLIQUITY_RAD Saturn’s axial tilt (obliquity) relative to its orbital plane: 26.73° SATURN_RING_A_OUTER_KM Saturn main ring outer edge (A ring): ~136,775 km from center SATURN_RING_INNER_KM Saturn ring inner edge (D ring): ~66,900 km from center SATURN_RING_OUTER_KM Saturn ring outer edge (F ring): ~140,180 km from center TITANIA_ORBITAL_RADIUS_KM Titania orbital radius: ~436,300 km URANUS_EQUATORIAL_RADIUS_KM Uranus equatorial radius: 25,559 km URANUS_OBLIQUITY_RAD Uranus axial tilt: 97.77° (retrograde rotation) URANUS_RING_OUTER_KM Uranus ring system outer edge: ~51,149 km ecliptic_z_height Compute the ecliptic z-height of a planet at a given Julian Date. max_ecliptic_z_height Compute the maximum ecliptic z-height a planet can reach. out_of_plane_distance Out-of-plane distance between two planet positions. saturn_ring_crossing Analyze whether a trajectory approaching Saturn crosses its ring plane. saturn_ring_plane_normal Compute the normal vector of Saturn’s ring plane in ecliptic coordinates. transfer_inclination_penalty Transfer inclination analysis: given departure and arrival planet positions,
compute the required inclination change and associated ΔV penalty. uranus_approach_analysis Analyze the approach geometry to Uranus from a given direction. uranus_spin_axis_ecliptic Compute Uranus’s spin axis direction in ecliptic coordinates.
