Alpha Delphini (α Del / α Delphini) is a multiple star in the constellation Delphinus.

Alpha Delphini has seven components: A and G, a physical binary, and B, C, D, E, and F, which are optical and have no physical association with A and G.


Beta Delphini, also known as Beta Del, is a multiple star in the constellation Delphinus. As a practical joke, the astronomer Niccolò Cacciatore gave it the name Rotanev, which is a reversal of his Latinized family name, Venator. The star has five components; components A and B are a physical binary; C, D, and E are optical.


Epsilon Delphini (ε Del / ε Delphini) is a Blue-white giant star approximately 358 light-years away in the constellation Delphinus. It also has the traditional name Deneb Dulfim which is Arabic for "tail of the Dolphin." The star is slightly variable, occasionally brightening to magnitude 3.95. ذنب الدّلفين
