It was discovered by William Herschel in 1782. 1826: 0.9 @ 23. Over 100 measurements. The orbit takes 34.487 years (Baize,

1976) with a semi-major axis of 1.36" and retrograde motion. Star A is a spectroscopic binary with a 10.5 year period and 1.14 solar masses. It is also an infra-red source. Star B is 0.82 solar masses.

The A star has already left the Main Sequence. Since it is almost the same mass as the Sun, it serves as a model of what the Sun will some day evolve into.

The system belongs to the Zeta Her group. Observations:

C8 at 280x. Chris Peters (Rio Rico, AZ; 8" Newt)— magnification of 358x, "showed the star elongated in an almost N-W line with the fainter star to the N." Both looked Y. Webb saw them as Y and R.
