The earth may , therefore , be regarded as the centre of a force which extends to the moon ; and , as experience shows that the action and reaction of matter are equal and contrary ( N. 19 ) , the moon must attract the earth with an ...

The mean distance of a planet from the sun is equal to half the major axis ( N. 42 ) of its orbit : if , therefore , the planet described a circle ( N. 43 ) round the sun at its mean distance , the motion would be uniform , and the ...

It has been observed , that the radius vector of a planet , moving in a perfectly elliptical orbit , passes over equal spaces or areas in equal times ; a circumstance which is independent of the law of the force , and would be the same ...
