How to get 2 game objects rotate around another game object in unity c#,

Using cos and sin method. the 2 game objects are 2 planets that rotate around another game objects.
The 2 planets need to be space out apart so that you can get 4 planets or game objects rotate the middle object.

using UnityEngine;
using System.Collections;

public class Sun : MonoBehaviour {

public GameObject[] planets;
private int array_size = 2;
private Vector3 obj_pos;
public GameObject a_gameobject;
private float x, y, z;
private float t;

private GameSystem gs_script;

private int ring_count = 2;

void Awake() { Debug.Log ("SUN Script: AWAKE"); gs_script = GameObject.Find("GameSystem").GetComponent<GameSystem>(); }
void Start()
{
	Debug.Log ("SUN Script: START");
	array_size = 3;
	planets = new GameObject[array_size];

	for(int i = 0; i < planets.Length; i++)
	{
		obj_pos = gameObject.transform.position;
		//a_gameobject = GameObject.Find("Planet");
		GameObject temp_go = Instantiate (a_gameobject, obj_pos, Quaternion.identity) as GameObject;
		temp_go.transform.position = obj_pos;
		temp_go.gameObject.name = "Planet " + gs_script.planet_count;
		planets *= temp_go;*

  •   	//Debug.Log("Planet " + i);*

  •   	//gs_script = GameObject.Find("GameSystem").GetComponent<GameSystem>();*

  •   	gs_script.planet_count = gs_script.planet_count + 1;*

  •   }*
  • }*
  • // Update is called once per frame*
  • void Update () {*
  •   t = t + Time.deltaTime;*

  •   //int i = 0;*

  •   for(int i =0; i < planets.Length; i++)*

  •   {*

_ PlanetRotate(planets , i);_

I kind of figured it out, a sung with 4 planets rotating the sun in 4 quadrents.

if (x0 > 1 || x0 < 1) { x0 += 0.5f; } x0 = Mathf.Cos (t * 2); y0 = 1; z0 = Mathf.Sin (t * 2);
planets[0].transform.position = new Vector3 (x0, y0, z0);

	//float x1, y1, z1;
	if (x1 > 1 || x1 < -1) { x1 += 0.2f; } x1 = -Mathf.Cos (t * 2); y1 = 1; z1 = -Mathf.Sin (t * 2);
	planets[1].transform.position = new Vector3 (x1, y1, z1);

	if (x2 > -0.5f || x2 < -0.5f) { x2 += 0.1f; } x2 = Mathf.Cos(t * 3); y2 = 1; z2 = Mathf.Sin (t * 3);
	planets[2].transform.position = new Vector3 (x2, y2, z2);

	if (x3 > -0.5f || x3 < 0.5f) { x3 += 0.3f; } x3 = -Mathf.Cos(t * 4); y3 = 1; z3 = -Mathf.Sin (t * 4);
	planets[3].transform.position = new Vector3 (x3, y3, z3);

Thanks any way.
