HR 1205
Scientific overview
HR 1205 is a red giant in the constellation Camelopardalis (Camelopardalis), lying about 1,462.6 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.
