Kapteyn's Star

The star is 30% of the diameter of the Sun but just 1.2% as luminous. It may have been used to be part of the globular cluster Omega Centauri. In 2014, two planets, Kapteyn b and Kapteyn c, were thought to orbit the star. but had a mix of disagreements and agreements, but a study in 2021 showed that both "planets" were just effects of the star's rotation and activity.
