The orbital characteristics are calculated from the epoch of 4 January 2010, at which time 739 Mandeville had an orbital period of 1656 days and an orbital axis of 2.74 AU with eccentricity 0.14. Thus, its minimum distance from the sun was 2.35 and its maximum was 3.13. Its orbital inclination was found to be 20.71°, and its mean anomaly 116.58°.
