How to Shot An Object Toward Mouse's Position

Hello? I’m a student in Korea… I’m making a puzzle game. but I have a mistake can you teach me how to make an object is shot to mouse’s position. this is my script.
public class aster : MonoBehaviour {
public Vector2 MousePosition;

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
	MousePosition = Input.mousePosition;
	Physics.gravity = Vector3.zero;

	if (Input.GetMouseButtonUp(0)) {
		GetComponent<Rigidbody>().AddForce(MousePosition);
	}
}

void OnCollisionExit(Collision collision){
	GameObject.Find ("Stellar").SendMessage ("Out");
}
