Michael, thanks for the answer!

Yes, the solution you suggested I tried at the very beginning.
But, unfortunately, this solution gives a very approximate result, there is no exact match with the array of points (which were formed earlier as an array along a curve, an ellipse) ...

Well, well, let it be as it is ... I will correct it manually;)))

Hi krass, if you need to match another array along curve maybe a good way would be to replicate a point object with array along curve along each one, and then you can use those points to snap on to with Transform > Orient > Orient line to line to make copies.

I seem to have found a solution intuitively.
Not sure why, but it worked.

So, I am creating a circular array as you said.
At the same time, I had to make the rectangle a little higher in height.
And then I scale it horizontally to the outer border of the balls... and all the rectangles are located exactly opposite the balls.



Now I can trim off the extra length of the rectangles - the orange ellipse and the green circle.
It seems to have worked out as it should!

The only thing is that after trimming the rectangles will no longer be rectangles. In my case, this is insignificant, but if these are curves of a different shape, this method will no longer work, alas ..

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
