Two grade 2 orbits. Left: orbit for HIP 40167 = WDS 08122+1739 = ζ₂ Cnc = HR 3210. Cb has completed 3.3 laps of its 17.3 yr period around Ca. The components have V magnitudes of 6.15 and 9.16 with spectral types G8 IV and M1 V, respectively, and ΣM = 2.69  ±  0.21 M_⊙. Right: orbit for HIP 43766 = WDS 08549+2612. Two and a half laps of its 45.3 yr period have been observed. The components have V magnitudes of 6.97 and 8.42 with spectral types G7 IV and G6 V, respectively, and ΣM = 2.63  ±  0.36 M_⊙.
