There are 200 billion stars in the milky way, with 90 percent of them being main sequence, most of these are sun like. (I cannot find any solid information that says the sun is anything but the perfect example of the average main sequence. Bigger stars die quickly, smaller stars are nearly invisible to us [dwarfs].) This means 180 billion stars are like the sun, but due to uncertainty, and tiny size of most of these, on a personal educated Hypothesis, I believe there to be about 100 billion stars that are sun-like and stable enough to support a solar system.
