Although the apparent diameters of the satellites are too small to be measured , yet their perturbations give the values of their masses with considerable accuracy - a striking proof of the power of analysis .

And , as the lunar theory gives the ratio of the forces , the ratio of tbe distances of the sun and moon from the earth is obtained . Hence it appears that the sun's mean distance from the earth is 399.7 or nearly 400 times greater than ...
