The Summer Triangle consists of three bright stars – Vega, Deneb and Altair – in three separate constellations. If you can find the Summer Triangle, you can use it to locate three of the sky’s smallest constellations: Vulpecula the Fox, Delphinus the Dolphin and Sagitta the Arrow. ~ EarthSky Tonight
