 A name given to the box shape formed by the four stars Alpha, Beta, Gamma and Delta Delphini, all of which are of 4th magnitude.

Gamma Delphini

 A double star. A small telescope will separate the two components, which appear yellow and white, of magnitudes 4.3 and 5.2. Both stars lie approximately 100 light-years away. A fainter and closer pair of 8th-magnitude stars, known as Struve 2725 (about 125 light-years away), should be visible in the same field of view.
