    The earliest solution of the inverse-square orbit problem was evidently constructed by John Keill and published in the 1708 volume of thePhilosophical Transactions. The latest published solution, so far as I am aware, can be found in Robert Weinstock, “Inverse-square orbits: Three little-known solutions and a novel integration technique,”Am. J. Phys. 60 (1992) 615–619.CrossRefzbMATHMathSciNetGoogle Scholar

    If, instead of erecting the perpendicular toOp at its midpoint in Fig. 1 (as does J/G2), we constructed the perpendicular toOp at, say, 0.75 of its length from O, and considered the pointP′ at which this perpendicular intersectsCp, then, as θ increases from 0 to 2π, the intersection P′ would still trace a closed smooth curve. However, you will find the tangent to this curve at each P′ is not (except for θ = 0 and θ= π perpendicular to the segmentOp. Only the choice of the halfway pointP works.Google Scholar
