Pi Phoenicis
Scientific overview
Pi Phoenicis is a red giant in the constellation Phoenix (Phoenicis), lying about 287.36 light-years from Earth.
Class K. Cooler orange stars. Long-lived and abundant; many are stable hosts for planets. Such stars have surface temperatures around 3,700–5,200 K and appear orange to the eye.

Evolution
A red giant is an evolved star that has exhausted core hydrogen and expanded enormously, cooling at its surface as it fuses heavier elements in shells.
