Star system description: σ Cet
A double or multiple star system in Cetus.
Pair AB (345.6″; magnitudes 4.79 and 8.77) is the binocular candidate in the catalog model. Actual resolution depends on magnification and stability.
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.
