HD 217107 is a yellow subgiant star approximately 65 light-years away from Earth in the constellation of Pisces. Its mass is very similar to the Sun's, although it is considerably older. Two planets have been discovered orbiting the star: one is extremely close and completes an orbit every seven days, while the other is much more distant, taking eight years to complete an orbit. HD 217107 is fairly close to the Sun: the Hipparcos astrometric satellite measured its parallax as 50.71 Milliarcseconds, which corresponds to a distance of 65 light years.
