How Many Stars to Search? The number of star systems that a SETI search would have to investigate before achieving success depends on how common signaling societies are in the galaxy. This is the number estimated by the Drake equation. Suppose this number is N = 1 million. How many star systems must be checked out by SETI in order to find one signal? What if N = 1000? Assume that there are roughly 100 billion stars in our galaxy.
