A long-period variable star of the type Mira Ceti, the brightest in this constellation. It lies near a small triangle of stars θ, σ and ρ And. At its maximum of 5.8mag it is at the limit of naked-eye visibility, but in 409.33 days its brightness drops to 14.9mag (changing by 9 magnitudes) and is virtually unobservable with smaller amateur telescopes. The distance is not precisely determined, about 790 light years.
