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.

What about using the gameobject attach to your collider while it’s trigger ?

void OnTriggerEnter2D(Collider2D other)
{
    planet = other.gameObject;
    attracting = true;
}
