Star system description: σ² Gru
A double or multiple star system in Grus.
Pair AC (337.9″; magnitudes 5.88 and 6.29) 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.
