How to configure camera to follow satellite and keep looking at Earth in 3D scene

[hahaxxz]

I'm creating a 3D scene where a satellite orbits around the Earth, and I want to set up the camera to follow the satellite's movement while constantly facing the Earth (to simulate the perspective of the satellite observing the Earth).
Is this achievable, and if so, could anyone guide me on the correct configuration steps?
I have already tried setting the camera's follow mode to target the satellite node and setting look at to the Earth node, but the result is not ideal
Any suggestions or code examples for implementing this camera behavior would be greatly appreciated!

What does the Viewfinder (the bottom editor tab that says Phantom Camera) show in the editor before you run the scene?

Does that look correct?

Thanks for your reply. I think the viewfinder looks fine.

But this is not the case after running.

My bad. I set the satellite's orbit radius too small—it must have ended up smaller than the Earth's radius. It works perfectly now!
This plugin is absolutely fantastic. I achieved exactly the effect I wanted without writing a single line of code. Thank you for all your hard work!

Glad to hear it was a simple fix!
Hope your project works out great :)
