	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.	Pnd1832A
	Castor A is also reported to exhibit x-ray and radio emission.
	See Baize & Petit (1989) catalog of doubles with variable component.	Baz1989d
	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.	Hei1960a
