Things changed when Jupiter turned into a black hole. It still orbits the sun and the Galilean moons still orbit it, but there’s gravitational lensing now.

Specifically, with enough resolving power, you can see light from the Earth that has been bent 180° back to us, delayed by twice the light distance to Jupiter, about an hour.

It’s the ultimate security camera. Nowadays, there’s no safer place than outdoors while Black Jupiter is in the sky.
