kerel on Freenode lbracher: I can recommend the method twoline2rv from sgp4 to read the TLE and then skyfield, poliastro or sgp4 to propagate around the orbit. To determine the perigee you could then use the optimization functions from SciPy. I don't think there is a method which directly returns the next perigee.

kerel on Freenode lbracher: Here is an example for propagation with sgp4: https://gitlab.com/kerel-fs/jupyter-notebooks/blob/master/beresheet/Beresheet.ipynb
kerel on Freenode If you implement a method for next perigee I would be interested as well (might use it to follow Beresheet :D).
