There are a lot of good binary pairs out there, and one of the best is in the often overlooked constellation Delphinus. Gamma Delphini is easily found at the “nose” of this little constellation. It has a magnitude of 4.27 and is about 101 light years away. And it is made up of a yellow-white dwarf star and and orange subgiant. There is speculation that the orange subgiant may harbor a planetary system. So the next time you’re exploring the Summer Triangle, just look a bit to the east for this binary treat.
