The long-period variable star of Mira Ceti type, the brightest in this constellation. It is located near the small triangle of stars θ, σ, and ρ And. At its maximum brightness of 5.8 mag, it is on the edge of visibility to the naked eye, but over 409.33 days its brightness decreases to 14.9 mag (thus changing by 9 magnitudes) and with smaller amateur telescopes it is practically unobservable. The distance is not precisely determined, approximately 790 light-years.
