Orbit object around parent object
I have been trying to rotate an object around it's parent but i cannot get it to work, the orbiting object is a child to the parent but when i run the game the child object does not move at all.
This is my script that is meant to have it rotate around the parent:
 using UnityEngine;
 using System.Collections;
 
 public class Orbit : MonoBehaviour {
 
     public float rotateSpeed = 5.0f;
     public float orbitSpeed  = 1.0f;
 
     private Vector3 pos;
 
     void Start(){
         //get parent object position
         pos = transform.root.gameOject;
     }
 
     void update() {
         // planet to spin on it's own axis
         transform.Rotate (transform.up * rotateSpeed * Time.deltaTime);
 
         // planet to travel along a path that rotates around the sun
         transform.RotateAround (pos, Vector3.up, orbitSpeed * Time.deltaTime);
     }
 }
 
               The script is a component attached to the child object that is meant to rotate.
I have no syntax errors either. Am using the latest version of Unity. What have I got wrong here?

First thing I notice is that the 'u' in your update function is lower case.
Should look like this :
 void Update() {
          // planet to spin on it's own axis
          transform.Rotate (transform.up * rotateSpeed * Time.deltaTime);
  
          // planet to travel along a path that rotates around the sun
          transform.RotateAround (pos, Vector3.up, orbitSpeed * Time.deltaTime);
      }
 
              Ah thanks good spot, i edited it and then got an error:
 Type `UnityEngine.Transform' does not contain a definition for `gameOject' and no extension method `gameOject' of type `UnityEngine.Transform' could be found (are you missing a using directive or an assembly reference?)
 
                  In relation to line:
         pos = transform.root.gameOject;
