I'm now trying the Orbiting camera around a object.

I tried this code here:
float deltaY=1;
Vector3 vec = new Vector3( 2f, 3f, 0f);
camera.rotateAround(vec, Vector3.Z, deltaY);

The camera movement works, but it rotates about its own axis.

How can I now to add a distance between the object and camera and then rotate the camera around the 3D object.

I tried so many variations without success.

public class Basic3DTest implements ApplicationListener {
    public PerspectiveCamera cam;
    public void create () {
        cam = new PerspectiveCamera(67,,;
        cam.position.set(10f, 10f, 10f);
        cam.near = 0.1f;
        cam.far = 300f;

Here we create a new PerectiveCamera with a field of view of 67 degrees (which is common to use) and we set the aspect ratio to the current width and height. Then we set the camera 10 units to the right, 10 units up and 10 units back. The Z axis is pointing towards the viewer, so for the viewer a positive Z value of the camera is moving the viewer back. We set the camera to look at (0,0,0) because that is where we are placing our 3D object to view. We set the near and far values to make sure we would always see our object. And finally we update the camera so all changes we made are reflected by the camera.
This was taken from I think it will help a lot for what your asking to do
