How do I move a 2d object to center of screen?

public float fallSpeed = 100.0f;

void Update() 
{
	
	transform.Translate(Vector3.down * fallSpeed * Time.deltaTime);
	
}

I currently have this code making my object fall down and it goes off the camera screen, I then want it to move to the center of the screen to which then it will activate a particle explosion. How would I go about doing that?

You can use Camera.ViewportToWorldPoint and pass it a Vector3 with x and y values = 0.5 (middle of viewport). The z values would determine the distance from the camera.
