3D plot of a massive ellipsoid?

In the excellent blog on the Rosetta Mission, Rosetta—First Mission to Orbit and Land on a Comet, examples of how to obtain 3D plots of both a massive cuboid and a massive ball are given. However, I am unable to determine how to modify these examples for the case of a massive ellipsoid. In the case of just an ellipsoid, one specifies the x,y,z positions and the ellipsoid dimensions. However, in the case of a massive ellipsoid the position coordinate trio appear to have dimensions of mass. Neither the massive cuboid nor the massive ball have this. Thus a simple application using Graphics3D doesn't work. I was attempting to modify the Rosetta Mission code to model an approach to 16 Psyche (i.e., the new NASA mission to an asteroid).

What do you mean with 'massive'? large? some snapshot or links or description would be very helpful.

I have attached the RossetaMission.cdf Using a "massive ellipsoid" enables one to calculate its gravitational potential. I am discussing a mathematica construct.
