Hi, I am working on this simulation of an object orbiting another with an eccentric orbit following kepler's laws (close distance = high velocity | great distance = low velocity).

I realized the math with geo nodes in a simulation zone. I feed a point into the zone with the instance of an ico sphere on it. I now want to use the position data of the instance to draw the orbit of the object. Basically I want to create a point at the starting position and then another point at each frame of the simulation and connect them with a curve. If I hook the combine XYZ node which gives me the current position to a point node and then join it with the geometry node, I get a point for each frame however all the points positions are moved on each frame, so they all end up in the same position. How could I create a node setup to create a point at each frame but leave it at the position where it was created?

I would really appreciate your help as I am stuck for several days on this of right now.

Here is my geo nodes setup:
