In the milky way galaxy there are between 200 billion and 400 billion starts.
With the kepler mission unraveling the nature of planets we conclude that per 200 billion stars, as an average there are 3 planets per star. (this assumes some stars have none, and some stars have up to 20+) So there are roughly between 600 billion and 1 trillion planets in the milky way galaxy.
Dont even get me started on moon because if we assume that out solar system's planet to satellite ratio is average of 25 satellites per planet. (25 x 800 billion = 20 trillion moons...)
