Its story

57 Ceti is a cool M-type red giant some 589 light-years away, immersed in the slow course of the Sea Monster s constellation. Its reddish light reaches magnitude 5.43, almost out of reach without clean, dark skies. Cetus stretches across the celestial equator, and among its stars lives the famed Mira, prototype of long-period variables —a reminder that this band of sky hides red giants in various stages of their slow agony.
