    Four tiny constellations to west are faint and not too famous

    UNION-TRIBUNE


    As the year draws to a close, the three bright stars of the famous
    Summer Triangle appear high above the western horizon shortly after
    dark.

    Near and among the stars of this large celestial grouping lie four
    small constellations. But don't think you'll be able to recognize
    these from just their names alone. These are some of the tiniest and
    faintest constellations in the heavens.

    The easternmost of the four is Equuleus, the Little Horse. It's an
    ancient group whose origins are shrouded in history.

    It was mentioned by the first century astronomer Claudius Ptolemy in
    his great book "Almagest" but, because Ptolemy borrowed much of his
    material from others, it might have actually been created by the
    Greek astronomer Hipparchus three centuries earlier. The
    second-tiniest constellation in the sky - and one of the faintest -
    Equuleus is difficult to see even under the darkest conditions.

    Just to its west lies Delphinus, an ancient constellation that
    represents the dolphin, and that probably originated in ancient
    Greece. When Poseidon, god of the sea, wanted to marry Amphitrite,
    she became so disgusted at the thought of living under the sea that
    she fled to the distant Atlas Mountains. Poseidon sent several
    messengers after her in hopes that she might return to him; only the
    dolphin Delphinus succeeded, and was rewarded by Poseidon with a
    place in the heavens.

    Sagitta, the Arrow, is the third-smallest constellation in the sky
    and, interestingly, is one of the few star patterns that actually
    looks like its namesake. Sagitta is an ancient constellation, and
    many cultures have seen an arrow outlined by its five faint stars.

    It has been identified as a stray arrow shot by Sagittarius, the
    archer, as one shot by Apollo to kill the Cyclops, or even as one of
    Cupid's arrows. Its name comes from ancient Hebrew, Armenian and
    Arabic, and all mean "arrow."

    Finally we find Vulpecula, the Fox, one of seven faint and relatively
    obscure Northern Hemisphere constellations created and introduced as
    "Vulpecula cum Anser" - Fox with Goose - by the Polish astronomer
    Johannes Hevelius in his 1690 atlas titled "Firmamentum Sobieski."

    It was in this constellation that, in 1967, astronomer Jocelyn Bell
    discovered the first pulsar - a rapidly rotating neutron star whose
    regularly pulsating radio signals led some (erroneously) to believe
    it was a message from an intelligent extraterrestrial civilization.
