I used array of just a single line, extending past the outer ellipse
Thren I can isect the outer ellipse with those lines to generate points.
Then I offset the outer ellipse in to the desired distance and trim the lines down to length
Then I run "FatLines" plugin to generate rectangles that are even on ends
Then I create a sphere on the side and run "CopyToPoints" on the sphere to get the spheres on the outer ellipse
