Variations of semi-major axis, eccentricity and inclination for a clone of 238P. Purple lines denote purely gravitational integrations, while pale-blue and green lines denote integrations which include NG interactions with P = 0.4 and 0.1 respectively. With A₂ < 0, the particle evolves inwards, NG forces also circularize the orbit. The integration is finished at perihelion distance q = 1.0 AU. The figure shows that NG forces are able to affect also eccentricity comparing to purely gravitational changes but they do not influence inclination.
