I remember reading an older book where they explained that planets get created when something disturbs the star which then ejects matter that forms into planets, and that was a reason why the planets are supposedly very rare to occur.
I think you are referring to the tidal hypothesis, It supposed another star passed so close to the sun that they they almost touched, each coming within the Roche radius of the other. The tidal interaction drew material off from each star which then coalesced to form the planets,
That is event so unlikely it probably happened just a handful of times across the entire milky way in the last 11 billion years.
