Its story

8 Piscis Austrini is a white A-type star 191 light-years away, in Piscis Austrinus —a small southern constellation dominated by the lonely Fomalhaut, the brilliant Mouth of the Fish—. It shines at magnitude 5.7, near the limit of unaided-eye visibility, and from Mediterranean latitudes barely lifts above the southern horizon on quiet autumn nights. Its steady white light quietly accompanies the far brighter Fomalhaut, like a candle beside a beacon.
