摘　　要：The increased velocity for the inner moon Phobos at Mars is calculated, assuming a modified gravity law with distributed mass. The motion of the moon is assumed to be balanced by the ＂close-force＂. The results from Stroberg, for planets in noncircular orbits, in conjunction with assuming a density, admit a balance equation for the rotation in a continuum flow. From this, explicit expressions for a velocity field and a so called Le-density are given. These are exploited to model distributed mass and formations, exemplified with a large asteroid, 2 Pallas, in the asteroid belt, bounds for the L-frequency, the formation of Mercury and distances between planets.
