AKA solar systems rare?
No. It seems that most stars have at least some sort of planetary debris around them. Currently, our detection methods are only sensitive enough to detect the rather extreme kinds of planetary systems (such as Jupiter-mass stars orbiting a half an AU from the star), but it's likely that Earth-like planets are not all that rare.
Since there's only one star called Sol, yes!

Not rare?, that is good news for me.
