TKS Ephemeris · heliocentric 3D

Solar system — real orbits of the planets around the Sun

Every planet placed and moved from its true heliocentric state vector (Engine A: DE440/DE441). Orbits are the real osculating ellipses computed from position & velocity; planets are 3D spheres; live orbital data updates on screen. Drag to rotate, scroll to zoom.

Notes. Planet sizes are exaggerated (not to scale); orbits & positions are to scale. Orbit = osculating ellipse from (r⃗, v⃗) at the epoch; animation propagates Kepler's equation from those elements (short-term, data-driven). λ, β = heliocentric ecliptic longitude/latitude. Engine A (reference DE path).
