Apoastron

[…]apoastra (i) and the circle of the periastra (2).

The initial Δv applied to them causes a large spread in the apoastra and in the orbital periods.

The rest of the plot shows the temporal evolution of the periastra and apoastra of the three planets using the nominal parameters on the left as initial conditions.

The planets’ masses are given in units of M_⊕ and the periastra, semimajor axes and apoastra are shown below.
