Proposed moderately eccentric polar orbit to gravitationally detect the Saturnian convective dynamo. The two panels plot the same thing from different viewing angles. The red line illustrates one closest approach of the Cassini Grand Finale orbits, with an inclination of about 57° and an eccentricity of almost 0.9. The black line draws an instantly osculating orbit of our proposed moderate-eccentricity orbits. The orbit takes a near-polar orientation, with 89° inclination. The minimum height from the Saturn cloud top at its periapsis is 6000 km, well inside of the ring system of Saturn. The orbital eccentricity is 0.5, which gives a 2 × 10⁵ km apoapsis. The two apsides lie in the equatorial plane of Saturn.
