HD 210702
HD 210702 is an orange subgiant star located approximately 177 light-years away in the constellation of Pegasus. With a mass of 1.8 times that of the Sun, the star spent its main-sequence life as an A-type star. The visual luminosity is 11.38 times that of the Sun and the magnitude is near the naked-eye limit, but binoculars can easily see it.The star shows variability in its radial velocity consistent with a planet-mass companion in a Keplerian orbit, and one was duly discovered in April 2007, from observations at Lick and Keck Observatories in Mount Hamilton and Mauna Kea, United States.
