Grab a variable from each planet in scene and put it into an array

Hi, I have a scene full of planets, and for something else I need to grab the variable "force" from a script called "Gravity2" attached to each of them and put those variables into an array called "Forces". I have tried a lot of things and I've just ended up confusing myself. The planets are the only non-GUI thing in the scene, and by planets I am talking about all objects with the tags "RedPlanet" "BluePlanet" "RedSun" "BlueSun" and "BlackHole". Just some ideas would be very helpful, thanks! Here is the script.

 #pragma strict
 
 function Start () {
 
 }
 
 function Update () {
 
 }
 
 static function CreatePath(a : float , v : float, x : float, obj : GameObject) : Vector3[]{
     var points : Vector3[] = new Vector3[4];
     
     //Creates Line
     for(var i : int = 0; i < 3; i++){
         var val : int = i + 1;
         points[i] = Vector3(val * v * Mathf.Cos(a), val * v * Mathf.Sin(a), 0);
         if(x > 0){
             points[i].x *= -1;
         }
     }
     for(var current in points){
         current += obj.transform.position;
     }
     //End Create Line
     
     //Add Net Force
         Forces(obj);
         
     //End Add Net Force
     
     return points;
 }    
 
 static function Forces(obj : GameObject){
 
     var planets : Array = GameObject.FindGameObjectsWithTag("BluePlanet");
     planets.Add(GameObject.FindGameObjectsWithTag("RedPlanet"));
     planets.Add(GameObject.FindGameObjectsWithTag("BlueSun"));
     planets.Add(GameObject.FindGameObjectsWithTag("RedSun"));
     planets.Add(GameObject.FindGameObjectsWithTag("BlackHole"));
     
     var forces : Array;
     
     if(planets.length > 0){
     
     
         for(var planet in planets){
             var planetGravity : Gravity2 = planet.gameObject.GetComponent("Gravity2");
             var force : Vector2 = planetGravity.force;
             
             forces.Add(force);
         }
     }
 }
