From: Exact solution to the problem of N bodies forming a multi-layer rotating structure
Multi-layer axisymmetric structure with N 2 = 15 and N 3 = 30; the angle φ j,1 = 0 alternates with the angle φ j,1 = 0.5·Δφ 0; P rd  = 1 year; r 1  = 1.493837 × 1011 m; m 1  = 9.172058 × 1029 kg and m SS  = 3.977302 × 1033 kg. The rest designations are the same as in Figure 2.
