Shapes of orbital paths...
orbits are very nearly circular,this is what i read. Could there be any chance of an exactly circular orbit,for all planets,if a square could be placed ontop of the circle.(so that the corners just touched the perimeter)highlighting line of sight,and also highlighting the return path of line of sight.Could it account for any discrepancies ie. elliptical paths?

helices as planmetary trajectories - a giant DNA molecule -one of many

The sun as the center of the solar system wheel pulls the orbiting planets with it as the sun orbits some mass center in the galaxy. Hence all the planets never orbited as circles and never will. Then trajectories of all the planets are helices - elipses and circles never close.
Kepler calculated the ellipses as projections only using data gathered by the Danish astronomer.
