Are the orientations of solar systems in this galaxy random? The question is related to discovering planets by the occlusion method. Looking at any star, the plane of that solar system must at 180 degrees to the observer in order to detect planets occluding that sun. Depending on the distance, there is a very slight angle possible, but basically we must see the solar system edgewise in order to detect planets crossing their solar disc. My point is, this circumstance must be very rare, yet we have discovered thousands of planets by this method, so that would indicate that there must be many times more planets 'in our neighborhood' that are not discoverable by this method.
