The thing is this: I originally created a ship to "imitate" the Cassini-Huygens, the section that would land on Laythe I separated it successfully, I was about to enter Laythe but it just touched the atmosphere and went off to Jool. Nor did he fall into the latter but accelerated a lot. The discussion is, is this normal? I have not been able to calculate to what percentage of the speed of light this speed corresponds; Here an image.
