Star system description: σ² Tau

A double or multiple star system in Taurus.

Pair AB (444″; magnitudes 4.69 and 5.09) is the naked-eye candidate in the catalog model. Seeing both stars separately depends on sky and eyesight.

The diagram uses the latest WDS measurements; north is up and east is right. Measurements may be from different years. Unconnected groups are arranged separately; close pairs may merge, and pairs without reliable geometry are omitted.
