The planets of our solar system revolve around the sun, tracing imaginary lines are called
orbits. These orbits are not perfectly round but are ellipses. Geometrically, the sun is not at the “center” of
the system, but one of the foci of the ellipse. The elliptical plane that contains these orbits is the ecliptic plane.
Heliospheric Planet Coordinates Heliocentric Trajectories for Selected Planets
Coordinates are available in Solar Ecliptic (SE) and Heliographic (HG)
(rotating and inertial) systems for 8 Planets, analytically propagated from
December 25, 1988.
They can be obtained at desired time period, and time resolution.
