| BNU 9 | 4 UMi. A spectroscopic binary, P = 605.8d, now resolved. | |
| Hipparcos astrometric solution adopted some elements from the orbit of | HIP1997d | |
| Scarfe (1971). | Scf1971 | |
| 1984.2791: Halbwachs (1981) predicts an angular separation of about | HJL1981 | |
| 0".03 and the system appears to be at the limit of resolution of the | ||
| 6-m telescope. | Bnu1986 | |
| Ren & Fu (2013) calculated an astrometric orbit, combining Hipparcos | Ren2013 | |
| Intermediate Astrometric Data with spectroscopic elements by | ||
| Scarfe (1971). | Scf1971 |
