Animation disturbing circular rotation

I have multiple child game objects making a circle around a parent game object also facing the parent gameobject. I also added an animation on the parent gameobject & the animation made the child gameobjects rotate on its Z axis instead of moving in a circle.

Vector3 v;
public GameObject go;
public Transform center;
public float degrees = -65;

void Start()
{
    v = transform.position - center.position;
}

void Update()
{
    v = Quaternion.AngleAxis(degrees * Time.deltaTime, Vector3.forward) * v;
    transform.position = center.position + v;

    Quaternion rot = Quaternion.LookRotation(go.transform.position - transform.position, transform.TransformDirection(Vector3.up));
    transform.rotation = new Quaternion (0, 0, rot.z, rot.w);
}

transform.rotation just changes the GameObject’s rotation. To make an orbit there is transform.TranslateAround: Unity - Scripting API: Transform.RotateAround
