How do I get an object to move from it’s current position A (transform.position) towards position B (a Transform variable) moving around Zero (Vector3.Zero)?
Here’s a mock up of what I have in mind:

Think of it like an airplane flying from one city to another across the surface of a sphere, the sphere is placed in zero.
Help will be much appreciated. Many thanks in advance.
Hey
You can slerp the object around the planet…
public Transform _origin;
public Transform _destination;
public Transform _planet;
public float journeyTime = 1.0F;
private float startTime;
void Start() {
startTime = Time.time;
}
void Update() {
Vector3 center = _planet.transform.position;
center -= new Vector3(0, 1, 0);
Vector3 riseRelCenter = _origin.position - center;
Vector3 setRelCenter = _destination.position - center;
float fracComplete = (Time.time - startTime) / journeyTime;
transform.position = Vector3.Slerp(riseRelCenter, setRelCenter, fracComplete);
transform.position += center;
}
