HD 188015 is an 8th magnitude star about 172 light-years away in the constellation of Vulpecula. It is a yellow subgiant, a Sun-like star that has ceased or is about to stop hydrogen fusion in its core. However, it is only slightly brighter than the Sun, but probably much older.
The star is almost twice as metal-rich as the Sun. Planets are common around such stars, and this star also has one known planet orbiting it.[1]
