c# script error for moving rigidbody to mouse position

I get this error error CS0120: An object reference is required to access non-static member `UnityEngine.Rigidbody.MovePosition(UnityEngine.Vector3)

from this script:
using UnityEngine;
using System.Collections;

public class Paddle_Behavior : MonoBehaviour 
{
	
	public int spin = 0;
	
	// Use this for initialization
	void Start () 
	{
		//deterime what paddle they are using
	}
	
	// Update is called once per frame
	void FixedUpdate () 
	{
		//move the paddle to the mouse point
		Rigidbody.MovePosition(Vector3(Input.mousePosition.x,Input.mousePosition.y,-10));
	}
}

Anyone have any idea why?

Rigidbody.MovePosition(Vector3(Input.mousePosition.x,Input.mousePosition.y,-10));

should be

Rigidbody.MovePosition(new Vector3(Input.mousePosition.x,Input.mousePosition.y,-10));

Please avoid this , posted right after first answer.
