Are stars with planetary systems very common or extremely rare?
Nolan AldridgeExoplanets are quite common.
More than 1000 exoplanets were confirmed in May 2016 alone, according to Wikipedia (https://tutor.hix.ai), and there may even have been exoplanet sightings outside the Milky Way Galaxy! On average, there is one planet for every star.
