minished in the ratio ( N. 16 ) of 1 to 3600 , which is the square of the moon's distance ( N , 17 ) from the earth's centre , estimated in terrestrial radii , it is found to be exactly the space the moon would fall through in the first ...

Should the force in the tangent cease , the planet would fall to the sun by its gravity . Were the sun not to attract it , the planet would fly off in the tangento Thus , when the planet is at the point of its orbit farthest from the ...
