These two quantities , however , will not give the place of a planet in space . Its distance from the sun ( N. 56 ) must also be known ; and , for the complete determination of its elliptical motion , the nature and position of its ...

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 .

... when compared with the time of the eclipse computed for Greenwich , or any other fixed meridian ( N. 95 ) , gives the difference of the meridians in time , and , consequently , the longitude of the place of observation .

And , as the lunar theory gives the ratio of the forces , the ratio of the 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 ...
