Great Comet of 1811 - ODEs solution

I have one solution of this problem

Great Comet of 1811 - Wikipedia

But my solution is in XY-coordinares and a nee in polar coordinates.

Help please

See pictures and the Prime 6 sheet

Here's a different way of looking at this (ODE's already solved analytically, as it's a two-body problem).

Thanks, Alan.

But the numerical solution more simple for the undestending.

And...

Solution without animation is not solution
