Arcturus is a type K0 III orange giant star, with an absolute magnitude of â0.30. It has likely exhausted its hydrogen from its core and is currently in its active hydrogen shell burning phase. It will continue to expand before entering horizontal branch stage of its life cycle.
The mass of Arcturus is hard to determine precisely, but may be slightly larger than that of the Sun (1.08 Â± 0.06 solar masses). Arcturus has been estimated to be around 6 billion to 8.5 billion years old, and has likely begun fusing helium into oxygen and carbon in its core.
