Problem with collider, rigidbody 2D

Questions & Answers

Hello
I’m writing to you in order to get help, because im beginner, and i’m stuck. I have 2 objects - bullet and asteroid, and my goal is that fired bullets has to destroy asteroid, but when i enter play mode bullets are just going through it and don’t interact.
To the asteroid i added components rigidbody2d set to kinematic and polygon collider 2d, and for bullet i added rigidbody2d component set to kinematic
Below I’m showing codes for both classes:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[RequireComponent(typeof(Rigidbody2D))]
[RequireComponent(typeof(Collider2D))]
public class Asteroid : MonoBehaviour
{
    [SerializeField]
    float Durability = 6f;
  
    void Start()
    {
        SetSpeed();
    }

    void Update()
    {
        
    }
    private void SetSpeed()
    {
        var targetSpeed = Random.Range(2f, 3f);
        GetComponent<Rigidbody2D>().velocity = Vector2.down * targetSpeed;
    }

    private void OnTriggerEnter2D(Collider2D collision)
    {
        var obj = collision.gameObject;
        var bullet = obj.GetComponent<Bullet>();

        if (bullet != null)
        {
            Durability--;
            Destroy(obj);

            if (Durability <= 0)
                Destroy(gameObject);
        }
    }
}

===============================================================================

using JetBrains.Annotations;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public enum CannonType { Single, Double, Triple }
[System.Serializable]

[RequireComponent(typeof(Rigidbody2D))]
[RequireComponent(typeof(SpriteRenderer))]
public class Bullet : MonoBehaviour
{
    [SerializeField]
    float Speed = 6f;

    public void Configure(BulletType bulletType)
    {
        GetComponent<SpriteRenderer>().sprite = bulletType.Sprite;
        GetComponent<Rigidbody2D>().velocity = transform.rotation * Vector3.up * bulletType.Speed;
    }

i’m sorry to bother, and kindly asking for help.
