How can I find the main.py file? about s.t.a.r HOT 1 CLOSED

Hi, thank you for pointing that out!
That was a mistake in the README.md. The name of the file is not main.py it is 2BodyProblem.py.
I have updated the readme with the change.

This is the main script which reads the TLE data, propagates the satellite and then overwrites the blender particle cache with satellite position data. After the script overwrites the cache data, you can open the earth.blend1 file in blender and it should animate the particles with the satellite position data from the particle cache.
