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.

Micro-wobbles can be detected at most angles to us, so the new and
improved Wobble methods for detecting planets should greatly help.


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

Swamped by Jupiter.

That's a very nifty gravity simulator program that amplifies "The
Solar System Barycenter" so that we get to see in detail what various
planets can do to their sun.
