Its story
Theta Ceti is a Horizontal Branch orange giant: a star that has already passed through the red giant phase and now lives in chemical calm, fusing helium at its core. About a billion years old, it shines with the light of fifty-seven Suns and its radius has swollen to nearly twelve times solar. It belongs to Cetus, the sea monster Perseus slew to rescue Andromeda.
