Does anyone know how to make the orbital tracker?
Just by pressing a button, he started to circle himself.

One simple way is to use Timer and Data Recorder.
Try to activate the Timerblock when you open the attached gh file.

Using Data Recorder and Mass Addition is far less than ideal for a timer. A better way is a Python timer from @AndersDeleuran:

In fact, if you have two Python timers on the canvas, both are affected by the shorter interval of the two. :frowning:

P.S. Here is a way to use it in your model:
