Wedged in between the bright star Fomalhaut (pronounced fo-ma-lo) to the south and the glittering Pleiades star cluster to the east is the huge, lumbering constellation of Cetus, the Whale. It ranks fourth in overall size among the 88 official constellations; only Hydra, Ursa Major and Virgo cover more area of the sky. Yet, despite its large size, Cetus claims no star brighter than second magnitude and has only one of those.
