Deneb, Altair and Vega

The Summer Triangle is an asterism in the northern celestial sphere formed from the stars Deneb, Altair, and Vega. During the summer months the triangle can be viewed directly overhead around midnight, but it is also visible during spring in the early morning and in autumn in the evening. Deneb lies in the constellation Cygnus the Swan and is the largest of the three stars. Altair is located in the constellation Aquila the Eagle and Vega belongs to the constellation Lyra the Lyre.

In Asia, there is a myth that surrounds this asterism. The Milky Way is referred to as the Celestial River and the common story behind the Summer Triangle is that there was a celestial princess, who weaves the fabric of heaven, named Orihime (Vega) and she fell in love with a a young herdsman Hikoboshi (Altair). The princess was so enamored with the herdsman that she accidentally neglected her weaving duties. Her father, the Celestial Emperor, found out about them and became so enraged that he forced Hikoboshi to live on the opposite side of the River in order to seperate the two lovers. The Emperor eventually gave in to the princess' pleas and allowed his daughter to meet with her beloved once a year on the seventh day of the seventh month. Deneb represents the flock of magpies that form a bridge to allow the herdsman to cross over the starry river. However, there are times when the journey through the Celestial River become too treacherous and Hikoboshi doesn't make it to their meeting. When this occurs, it is said that Orihime sheds tears in the form of rain here on Earth.

ACCURACY: The information on this site seems accurate and up to date since there have been no major changes in the asterism itself. The facts on the page are consistent with the information on other sites as well. It gives the names of the stars and the the constellations they belong to. Another good thing about this site is that it actually tells you how to find the Summer Triangle in the night sky by locating Cygus the Swan and working your way down it's "tail" to find Albireo, which is a star that is located roughly between Altair and Vega. It's a beautiful sight to behold and once you master finding Cygnus, you can always find the backbone of the Milky Way Galaxy.
