NotesAlrescha is known to be a binary system consisting of two white stars, with the companion star pursuing a 3,000-year orbit around the primary, and there is some evidence that one or both component stars may themselves be a close binary. The primary star Alpha Piscium A is variable of the α2 Canum Venaticorum type, showing changes in its level of brightness as the star rotates on its axis.
Location of Alrescha

Alrescha, the 'Cord' that binds together the two fishes of Pisces, falls close to the borders of Cetus, the Whale.

Just within the borders of Pisces, less than ten arcminutes from Cetus, lies Alpha Piscium or Alrescha. In mythology, Alrescha represented the place where a cord binding the two fishes of Pisces met. A complex and interesting place, Alrescha is not only a binary star system, but the primary star apparently has variations or markings of some kind on its surface.
