Psi-1 Draconis is a triple star system containing the spectroscopic binary Psi-1 Draconis AC, and their distant companion Psi-1 Draconis B. The radial velocities of Psi-1 Draconis B indicate the presence of a jovian planet on an eccentric, long-period orbit and a trend indicating the presence of an additional companion. The trend is not compatible with being caused by Psi-1 Draconis AC, so indicates the presence of an additional, likely substellar object outside the orbit of the known jovian planet.
