NotesThe designation '77 Piscium' applies not to a single star, but to a pair of faint yellow-white dwarfs separated by just half an arcminute in the sky (though in fact lying approximately one light year apart).

The two main stars that make up the 77 Piscium system can be easily distinguished in this image. 77 Piscium A is the brighter star to west (right), while 77 Piscium B is the slightly fainter of the pair to the east (left). As seen from Earth, the stars are separated by an angle of a little over half an arcminute. Imagery provided by Aladin sky atlas
