Kepler found , by direct observation , that the planets describe ellipses ( N. 24 ) , or oval paths , round the sun . Later observations show that comets also move in conic sections . It consequently follows that the sun attracts all ...

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 ...

Suppose two planets moving in ellipses round the sun ; if one of them attracted the other and the sun with equal intensity , and in parallel directions ( N. 62 ) , it would have no effect in disturbing the elliptical motion .
