What is Pi 2 Pegasi

Pi-2 Pegasi is a yellow-white giant that has burned through its core hydrogen and bloated to 8.5 times the Sun's radius, now shining with over a hundred solar luminosities. Despite its 530 million years it has held on to an unusually rapid spin—nearly thirty times the Sun's. At 263 light-years, it marks a quiet point on the neck of winged Pegasus.
