Star system description: 57 UMa

A double or multiple star system in Ursa Major.

Pair AD (344″; magnitudes 5.36 and 7.73) 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.
