30 Cygni (ÿ<sup>1</sup> Cygni) is a class A5III (white giant) star in the constellation Cygnus. Its apparent magnitude is 4.83 and it is approximately 610 light years away based on parallax.
The Bayer letter ÿ (omicron) has been variously applied to two or three of the stars 30, 31, and 32 Cygni. 30 Cygni has sometimes been designated as ÿ<sup>1</sup> Cygni with the other two stars being ÿ<sup>2</sup> and ÿ<sup>3</sup> respectively. For clarity, it is preferred to use the Flamsteed designation 30 Cygni rather than one of the Bayer designations.
30 Cygni is about six arc-minutes from 31 Cygni A and seven arc-minutes from 31 Cygni B. That pair is known as ÿ<sup>1</sup> Cygni, while ÿ<sup>2</sup> Cygni is a degree away. Both ÿ<sup>1</sup> and ÿ<sup>2</sup> are 4th magnitude stars.
