    Intro and Visual description

    Andromeda contains one corner of the Great Square of Pegasus (the star Alpheratz). Andromeda’s dress flows outward from the corner along three pairs of stars, with each pair slightly farther apart than the previous pair. Perhaps she is petting Pegasus, who bore the hero Perseus across the ocean on his mighty wings to save her from the sea monster Cetus.

  • Peg - Pegasus the Flying Horse

    Size

    7 of 88

    Regions

    Intro and Visual description

    Farther along on the line from the Pointers to Polaris and Cassiopeia is a large, nearly perfect square of four stars. This is the Great Square of Pegasus. Pegasus, the Winged Horse, lies almost directly overhead in autumn. Located east of Andromeda; signals the coming of Fall. Because Pegasus flies so fast, his hind quarters can’t be seen.

    Pegasus is included in the ancient star catalogs of Eudoxos of Knidos, Aratos of Soli, and Ptolemy.

     

     

    Skylore and Literature:  See Andromeda and Perseus.

  • Psc - Pisces the Fishes

    IAU Constellation

    Size

    14 of 88

    Intro and Visual description

    South of Pegasus and Andromeda, near Aquarius. Pisces represents two fish tied together by two cords:

    • The western fish, a pentagon of stars just south of Pegasus, is an asterism known as the circlet.
    • The other fish lies on the opposite side of Pegasus, just under Andromeda.

    The brightest star, alpha-Piscium, is known as El-Rischa or the "knot" because it ties the two cords together with the two fish on the opposite ends. Alpha-Piscium lies nestled up next to Mira, a bright variable star of the constellation Cetus the Whale.
