Abstract
HD 97810 is a 'Clube Selected Areas' binary system close to the north celes tial pole. It has a very eccentric orbit (e similar to 0.73) and a period o f 1164 days. Indirect evidence suggests a spectral type of K1 III. The obje ct has been catalogued and repeatedly measured as a very close, equal, visu al binary, but the author cannot see how to reconcile such a system with th e radial-velocity observations.
