How To Create An Array of instantiated objects? [Solved!]

Im instanstiating Some Random prefabs, and I need to store those prfabs in an array, how could i do that?

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.UI;
6. using Random = UnityEngine.Random;
7.  
8. public class MasterSpawner : MonoBehaviour
9. {
10.     public Image[] Pannels;
11.     public GameObject[] Plannets;
12.     GameObject[] PlannetsSave;
13.     bool UsedOnce = false;
14.     public void RandomizeAndInstanciate()
15.     {
16.         if (!UsedOnce)
17.         {
18.             UsedOnce = true;
19.             foreach (Image i in Pannels)
20.             {
21.                 int R = Random.Range(1, Plannets.Length);
22.                 GameObject GO = Plannets[R];
23.                 Instantiate(GO, i.transform.position, i.transform.rotation);
24.  
25.             }
26.         }
27.  
28.     }
29.  
30. }

 

Instantiate returns a gameobject. I would just add that to a list rather than an array as it looks like the size would be variable.

 

oh That Actually could be a way to do it, Il go try it out! thanks!

edit: Ive messed about with the code and got to this script after some time, Ive added these lines to my codes:
/// At the top
public List<GameObject> PlannetsSave = new List<GameObject>();
/// in the "Foreach" loop.
GameObject GOB = Instantiate(GO, i.transform.position, i.transform.rotation);
PlannetsSave.Add(GOB);

Thanks WarmedxMints!
