Gamma Apodis
Scientific overview
Gamma Apodis is a subgiant in the constellation Apus (Apodis), lying about 156.28 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.
