Gamma Coronae Borealis

[5] Based upon an annual parallax shift of 22.33[1] mas as seen from Earth, it is located about 146 light years from the Sun.

[8] The semimajor axis is 0.73 arc seconds − roughly the distance from the Sun to Neptune[13] − and the inclination of the orbital plane is 94.5°.

A year later, it was "confirmed" to be a δ Scuti variable with the earliest known spectral type in the class.

The observed variations were not strictly periodic, but showed a characteristic timescale of 0.03 days (43 minutes).

[16] γ Coronae Borealis also showed anomalous behaviour not seen in other δ Scuti stars, such as periods without variation.
