HD 147506, also known as HAT-P-2 and formally named Hunor, is a magnitude 8.7 F8 dwarf star that is somewhat larger and hotter than the Sun. The star is approximately 419 light-years (128 parsecs) from Earth and is positioned near the keystone of Hercules.[3] It is estimated to be 2 to 3 billion years old, towards the end of its main sequence life.[2] There is one known transiting exoplanet, and a second planet not observed to transit.[9]
