WASAT (Delta Geminorum). With a name that does not ring much of a bell among astronomers, and shining only at the bright end of fourth magnitude, neither does the star itself.
[3946] delta Geminorum, a binary star, has the traditional name Wasat ("the middle").
Pollux's pelvis is represented by star delta Geminorum, Pollux's right knee by zeta Geminorum, Pollux's right foot by gamma Geminorum, Pollux's left knee by lambda Geminorum, and Pollux's left foot by xi Geminorum.
Delta Geminorum: visual magnitudes 3.5, 8.2, PA 225º, separation 5.8". The period is estimated at 1200 years; the companion is an orange dwarf which may be difficult to resolve in smaller telescopes.
