Make Object Face Mouse Pointer

Good day,

I am currently designing a game, for which I need an object to face the mouse pointer. Can anyone tell me where I went wrong? Thanks a lot.

<!doctype html>
<html>
  <head>
    <meta charset="utf-8">
    <link rel="stylesheet" style="text/css" href="game.css">
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
    <script src="game.js"></script>
    <title>Rocket Game</title>
  </head>
  <body>
    <img id="rocket" src="rocket.jpg">
  </body>
</html>

#rocket {
  position: absolute;
  left: 250px;
  top: 200px;
}

var rocket = $("#rocket");
var rocketCenter=[rocket.offset().left+rocket.width()/2,
                  rocket.offset().top+rocket.height()/2];
$(document).ready(function(){
  $(document).mousemove(function(e){
    var angle = Math.atan2(e.pageX - rocketCenter[0], - (e.pageY - rocketCenter[1]) )*(180/Math.PI);        

      rocket.css({ "-webkit-transform": 'rotate(' + angle + 'deg)'});    
      rocket.css({ '-moz-transform': 'rotate(' + angle + 'deg)'});
      rocket.css({ 'transform': 'rotate(' + angle + 'deg)'});
  });
});

When i get you right you need the mouse showing the pointer when hover over the #rocket ? Then all you need to do is to add cursor:pointer; to your css

#rocket {
  position: absolute;
  left: 250px;
  top: 200px;
  cursor:pointer;
}

Hope this helps

No, I actually want the rocket to point to where the mouse is, wherever that may be. :)
