HD 187129 is listed as visual binary with a likely K5 to M giant (primary) companion 5,050 AUs away. ExoFOP TESS reports individual distances of 397.573 ± 7.314 pc and 354.215 ± 5.969 pc which do not seem to confirm physical association, however accounting possible uncertainties in distance estimate wide binarity is still possible.
