52 Cygni is a giant star in the northern constellation of Cygnus with an apparent magnitude of 4.22. Based on its Hipparcos parallax, it is about 291ly away.
52 Cygni is a probable horizontal branch (red clump) star, fusing helium in its core, although there is a 25% chance that it is still on the red giant branch (RGB) and fusing hydrogen in a shell around an insert core. As a clump giant it would be 2.27 billion years old, but only 910 million years if 52 Cygni is an RGB star. It shines with a bolometric luminosity of about at an effective temperature of 4,677 K. It has a radius of .
At an angular separation of 6.0″ from 52 Cygni is a faint magnitude 9.5 companion.
