discovered in 1719 by Bradley and Pound. Mt. Wilson spectral types |
Bdy1832A |
|
A2,A2,M1. A and B are both SB1's with P = 9.21 d and 2.93 d. |

Star C (mag. 9.1, M1Ve) is the spectroscopic and detached eclipsing |
|
|
binary YY Gem (P = 0.81 d), 70" from the center of AB and in slow |
|
|
retrograde motion (cf., Heintz), so the object is sextuple. |
