Many planets gravity attraction problem

Hello, im doing fake gravity towards center of planets using Sebastian Lague video tutorials. I managed to convert it to 2D, because im working in a 2D game. The thing is that everything works as expected but with just 1 planet on game. If i add more planets, it always take the last planet i added on the scene, maybe its because im just checking with tag, and all my planets have the same tag. How can i change it so the gravity force is towards the planet im touching the trigger.

This is the code:

 using UnityEngine;
 using System.Collections;
  
 [RequireComponent(typeof(Rigidbody2D))]
 public class GravityBody : MonoBehaviour
 {
     //Variables
     private GravityAttractor planet;
     private Rigidbody2D rb2D;
  
     public bool attracting = false;
  
     void Awake()
     {
         rb2D = GetComponent<Rigidbody2D>();
         planet = GameObject.FindGameObjectWithTag("Planet").GetComponent<GravityAttractor>();
         rb2D.gravityScale = 0;
     }
  
     void FixedUpdate()
     {
         if(attracting == true)
             planet.Attract(transform);
     }
  
     void OnTriggerEnter2D()
     {
      
  
     }
  
     void OnTriggerExit2D()
     {
         attracting = false;
     }
 }

planet = GameObject.FindGameObjectWithTag("Planet").GetComponent();

That part is the problem i think, becasue every planet in my game has that tag, so it just choose the last one i ad don scene.
