Deneb, Vega and Altair are part of what's called an asterism, a group of bright stars that aren't an official constellation. You can locate the Summer Triangle most times of the year, but it is most prominent in summer. Spotting the Summer Triangle can lead you to other stars. For example, Deneb, Vega and Altair are the brightest stars in their own constellations.
