It is faintly visible to the naked eye, having an apparent visual magnitude of +5.4.

[2] Based upon an annual parallax shift of 5.49 mas,[1] it is located roughly 590 light years from the Sun.

At that distance, the visual magnitude is diminished by an extinction of 0.1 due to interstellar dust.

[13] At its estimated distance, this yields a physical size of about 50 times the radius of the Sun.

[6] Nu2 Coronae Borealis is radiating 530[7] times the Sun's luminosity from its photosphere at an effective temperature of 3,940 K.[8]
