I agree with you here. Now if Barnard's star was ejected from a system, will it have a planet?

I suspect *all* stars have planets, and to be without is exceptional. The planets we can detect further away, have to have their ecliptic aligned pretty close to Earth for us to see them occulting their parent.

Just for asking; How much does the gravitational
pulls of Venus or even little Mercury wobble our
sun?

Swamped by Jupiter.
