The primary is an unresolved binary, also an Alpha CVn type variable, P = 1.74 d, and an astrometric, spectroscopic, and spectrum variable (Rakos, Lowell Obs. Bull. 5, 227, 1962; Klock, AJ 70, 176, 1965). The RV variation has not been confirmed. Heintz (1962) also detected this pair as a submotion to the visual Hei1962 orbit of the AB pair with a period of 52 years and an amplitude of 0".11. Star C (mag. 8.4, dG4) is probably physical, but Hopmann Hop1960b (1960) computed a hyperbolic orbit for it, as there is some RV difference between C and A. q = periastron distance in the true orbit = 6".7056.

Star B is W UMa-type eclipsing SB2; P = 0.2678 d (Popper Ppp1943 1943; Binnendijk 1955, AJ 60, 355, 1955). The RV of pair B differs by +30 km/s from that of star A, much more than the visual motion can effect, and thus does not represent the true mass-center velocity of B. The eclipsing period undergoes intrinsic changes considerably larger than a lighttime effect in the orbit AB. Attempts to identify the ascending node are thus unreliable: Time shifts of light minima suggest the first quadrant (Plaut), the RV difference the third quadrant (Heintz).
