Star A is a spectroscopic binary and an infra-red source. Its components are 2.2 and
1.8 solar masses.
The AB orbital period is 26.65 years (Couteau, 1962), with semi-major axis of 0.447"
and direct motion. Apasteron appeared in 1977 and will recur in 2004. Motion is direct.
Burnham discovered this pair in 1873.
