Its orbit is a more eccentric than Hygiea (15% versus 12%) but is different because Hygiea's orbit is much more inclined and takes less time to complete one orbit. Another difference is that Interamnia's perihelion is at the other side of the perihelia of the "big four", so that Interamnia at perihelion is actually closer to the Sun than Ceres and Pallas are at the same longitude. It is unlikely to collide with Pallas because their nodes are located too far apart. Although its nodes are located on the opposite side from those of Ceres, it is generally far from Ceres when both cross the same orbital plane and a collision is again unlikely.
