Name the constellation in the Northern hemisphere that contains the very bright star Vega, a part of the summer triangle?
Summer Triangle Summer Triangle The Summer Triangle is an astronomical asterism in the northern celestial hemisphere. The defining vertices of this imaginary triangle are at Altair, Deneb, and Vega, each of which is the brightest star of its constellation (Aquila, Cygnus, and Lyra, respectively). The term was popularized by American author H. A. Rey and British astronomer Patrick Moore in the 1950s. The name can be found in constellation guidebooks as far back as 1913. The Austrian astronomer Oswald Thomas described these stars as "Grosses Dreieck" (Great Triangle) in the late 1920s and "Sommerliches Dreieck" (Summerly Triangle) in 1934. The asterism was
Summer Triangle the "Navigator's Triangle". From mid-northern latitudes, the Summer Triangle appears virtually overhead around midnight during summer. It is also visible in the eastern sky in early mornings during spring. In autumn evenings, the Triangle is visible in the western sky well until December. From mid-southern latitudes, the asterism appears inverted, with Deneb below Altair, and low in the sky during winter.
