C. ; Elsasser, W. M. ; Rochester, M. G. Abstract The irregular shape of the moon can be explained by assuming that its density varies with angular position and possibly also with the radius, and it is shown that great strength in the deep interior is not required in this model. The outer parts must have great strength in order to account for certain surface irregularities. It is suggested that the external parts are now, and have been since the surface features were established, colder and hence more rigid than those of the earth. The irregularities in density indicate that some masses of matter of variable density were required in the moon's formation. The variable density is inconsistent with its accumulation from small objects only or with a generally hightemperature state at any time.
