Antinous is an obsolete constellation no longer in use by astronomers, having been merged into Aquila, which it bordered to the North. Aquila constellation, its name is Latin for eagle and it represents the bird who carried Zeus/Jupiter's thunderbolts in Greco-Roman mythology. Aquila lies just a few degrees North of the celestial equator. Delphinus constellation is close to the celestial equator. Its name is Latin for dolphin. It is one of the smaller constellations, ranked 69th in size. Delphinus' brightest stars form a distinctive asterism that can easily be recognized. Vulpecula is a faint constellation. Its name is Latin for little fox, although it is commonly known simply as the fox. It was identified in the seventeenth century, and is located in the middle of the Summer Triangle (an asterism consisting of the bright stars Deneb, Vega and Altair).
